PART – C

Answer the following questions in a paragraph.

Question 28.
What are the motives of demand for money?
Answer:
Motives of Demand for Money:
According to Keynes, there are three motives for liquidity preference. They are:

1. The Transaction Motive:

• The transaction motive relates to the desire of the people to hold cash for the current transactions.
• The amount saved under this motive depends on the level of income.
• M_t = f(y)

2. The Precautionary Motive:

• The precautionary motive relates to the desire of the people to hold cash to meet unexpected or unforeseen expenditures such as sickness, accidents, fire and theft. The amount saved for this motive also depends on the level of income.
  M_p = f(y)

3. The Speculative Motive:
The speculative motive relates to the desire of the people to hold cash in order to take advantage of market movements regarding the future changes in the price of bonds and securities in the capital market. The amount saved for this motive depends on the rate of interest.
M_S = f(i). There is inverse relation between liquidity preference and rate of interest.

Question 29.
List the kinds of wages.
Answer:
1. Nominal wages or money wages :
Nominal wages are referred to as the wages paid in terms of money.

2. Real wages :
Real wages are the wages paid in terms of goods and services. Hence, real wages are the purchasing power of money wages.

3. Piece wages :
Wages that are paid on the basis of quantum of work done.

3. It enters into the price.	It does not enter into price.

Question 31.
Briefly explain the Subsistence Theory of Wages.
Answer:

• Subsistence theory was first explained by physiocrats and restated by Ricardo.
• According to this theory, wage must be equal to the subsistence level of the labourer and his family.
• If workers are paid higher wages they would be better off and will have large families. Hence, the population would increase, which results in increased supply of labourer and so wages will come down.
• If wages are lower, there would be a reduction in population and thereby the supply of labour falls and wages increase to the subsistence level.
• This theory holds that the wages of workers would not be above or below the subsistence level of the labourer and his family.

Question 32.
State the Dynamic Theory of Profit?
Answer:
Dynamic Theory of Profit:

• J.B. Clark propounded this theory in 1900. To him, profit is the difference between price and cost of production of the commodity.
• Profit is the reward for dynamic changes in society. He points out that, profit cannot arise in a static society. In static society, everything remains stationary.
• The following changes take place in a dynamic society.
  1. The population is increasing.
  2. The volume of capital is increasing.
  3. Methods of production are improving.
  4. Forms of the industrial organization are changing.
  5. The wants of consumers are multiplying.

Question 33.
Describe briefly the Innovation Theory of Profit.
Answer:

• Innovation theory was propounded by Joseph. A. Schumpeter.
• Profit is the reward for “Innovation”. Innovation means invention put into commercial practice.
• An innovation may consist of:
  1. Introduction of a new product.
  2. Introduction of a new method of production.
  3. Opening up of a new market.
  4. Discovery of new raw materials.
  5. Reorganization of an industry/firm.
  6. Anyone of these innovations leads to a reduction in the cost of production and thereby brings profit to an entrepreneur.

Question 34.
Write a note on the Risk-bearing Theory of Profit?
Answer:

• Risk – the bearing theory was propounded by F.B.Hawley in 1907.
• Profit is the reward for “risk-taking” in business.
• Every business involves some risks. So risk-taking is an essential function of the entrepreneur and is the basis of profit.
• Higher the risks, the greater are the profit.
• Profit induces entrepreneurs to undertake risks.

Question 35.
Explain the Marginal Productivity Theory of Distribution?
Answer:
Introduction:

1. This theory was developed by Clark, Wicksteed and Walras. The Marginal productivity theory of distribution explains how the prices of various factors of production are determined.
2. This theory explains how rent, wages, interest and profit are determined.
3. This theory is also known as the “General Theory of Distribution ” or “ National Dividend Theory of Distribution”.

Assumptions:

1. All the factors of production are homogenous.
2. Factors of production can be substituted for each other.
3. There is perfect competition both in the factor market and product market.
4. There is perfect mobility of factors of production.
5. There is full employment of factors.
6. This theory is applicable only in the long-run.
7. The entrepreneurs aim at profit maximization.
8. There is no government intervention in fixing the price of a factor.
9. There is no technological change.

Explanation of the Theory:
According to the Marginal Productivity Theory of Distribution, the.price or the reward for any factor of production is equal to the marginal productivity of that factor. Each factor is rewarded according to its marginal productivity.

Marginal Product:
The Marginal Product is also known as “ Marginal Physical Product “ [MPP]. The Marginal Product of a factor of production means the addition made to the total product by the employment of an additional unit of that factor. The Marginal Product may be expressed as MPP, VMP, and MRP.

1. Marginal Physical product [MPP]: The Marginal Physical Product of a factor is the increment in the total product obtained by the employment of an additional unit of that factor.

2. Value of a marginal product [VMP]: The Value of Marginal Product is obtained by multiplying the marginal physical product of the factor by the price of the product. Symbolically VMP = MPP × Price

3. Marginal Revenue product [MRP]: The Marginal Revenue Product of a factor is the increment in the total revenue which is obtained by the employment of an additional unit of that factor.
MRP = MPP × MR

The Marginal Productivity Theory of Distribution states that

1. The price of a factor of production depends upon its productivity.
2. The price of a factor is determined by and will be equal to the marginal revenue product of that factor.
3. Under certain conditions, the price of a factor will be equal to both the average and marginal products of that factor.

Question 36.
Illustrate the Ricardian Theory of Rent?
Answer:

1. The Classical Theory of Rent is called the “Ricardian Theory of Rent.”
2. “ Rent is that portion of the produce of the earth which is paid to the landlord for the use of the original and indestructible powers of the soil” – David Ricardo

Assumptions:
Ricardian theory of rent assumes the following:

1. Land differs in fertility.
2. The law of diminishing returns operates in agriculture.
3. Rent depends upon fertility and location of the land.
4. The theory assumes perfect competition.
5. It is based on the assumption of a long period.
6. There is the existence of marginal land or no-rent land.
7. The land has certain “Original and indestructible powers”.
8. The land is used for cultivation only.
9. Most fertile lands are cultivated first.

Statement of the Theory with Illustration:
There are three grades of land, namely A, B, and C on that island. ‘A’ being most fertile ‘B’ less fertile and ‘C’ the least fertile. They will first cultivate all the most fertile land. The yield per acre on ‘A’ grade land is 40 bags of paddy.

The same amount labour and capital employed in ‘A’ grade land. The yield per acre on ‘B’ grade land is 30 bags of paddy.
The Surplus of 10 bags [40-30] per acre appears on ‘A’ grade land. This is “ Economic Rent” land of ‘A’ grade land.

The yield per acre on ‘C’ grade land is 20 bags of paddy. This surplus of ‘A’ grade land is now raised to 20 bags [40-20] and it is the “ Economic Rent” of ‘A’ grade land.

The ‘C’ grade land, cost of production is just equal to the price of its products and therefore does not yield any rent [20-20], Hence, ‘C’ grade land is called ‘no-rent land or marginal land ’. The land which yields rent is called “intra-marginal land”.

Diagrammatic Explanation:

1. In the diagram, X-axis represents various grades of land, and Y-axis represents yield per acre [in bags],
2. OA, AB, and BC are the ‘A’ grade ‘B’ grade and ‘C’ grade lands respectively.
3. The ‘C’ grade land is the no rent land.”
4. ‘A’ land ‘B’ grade lands are “intra – marginal lands”.
5. The economic rent yielded by ‘A’ and ‘B’ grade lands is equal to the shaded area of their respective rectangles.

Question 37.
Elucidate the Loanable Funds Theory of Interest?
Answer:

1. The loanable fund’s theory, also known as the “Neoclassical theory”. This theory was developed by Swedish economists like Wicksell, Bertilohlin, Viner, Gunnar Myrdal, and others.
2. Interest is the price paid for the use of loanable funds.
3. The rate of interest is determined by the equilibrium between the demand for and supply of loanable funds in the credit market.

Demand for loanable funds :

1. Demand for Investment (I)
2. Demand for Consumption (C)
3. Demand for Hoarding (H)

Supply of loanable funds :
1. Savings (S) :
Savings may be of two types, namely.

1. Savings planned by individuals are “ex-ante savings”. (Eg.) LIC premium
2. Unplanned savings are called “ex-post savings”

2. Bank credit:
Commercial banks create credit and supply loanable funds to the investors.

3. Dishoarding (DH) :
Dishoarding means bringing out the hoarded money into use and thus it constitutes a source of supply of loanable funds.

4. Disinvestment (DI):
Disinvestment is the opposite of investment. It means not providing sufficient funds for the depreciation of equipment.

Explanation:
The X-axis represents the demand for and supply of loanable funds, Y-axis represents the rate of interest. The LS curve represents the total supply curve of loanable funds. The LD curve represents the total demand for loanable funds. The LD and LS curves, intersect each other at the point “E” the equilibrium point. At this point OR rate of interest and OM is the number of loanable funds.

Criticisms :

1. Many factors have been included in this theory’. Still, there are many more factors like
   • Asymmetric information
   • Moral Hazard.
2. It is very difficult to combine real factors with monetary factors.

Question 38.
Explain the Keynesian Theory of Interest?
Answer:
Keynes’ Liquidity Preference Theory of Interest or The monetary Theory of Interest

1. Keynes propounded the Liquidity Preference Theory of Interest in his famous book,
   “ The General Theory of Employment, Interest, and Money “ in 1936.
2. According to Keynes, interest is purely a monetary phenomenon because the rate of interest is calculated in terms of money.
3. “Interest is the reward for parting with liquidity for a specified period of time”.

Meaning of Liquidity Preference:

1. Liquidity preference means the preference of the people to hold wealth in the form of liquid cash rather than in other non-liquid assets like bonds, securities, bills of exchange, land, building, gold etc.
2. “Liquidity Preference is the preference to have an amount of cash rather than of claims against others”. – Meyer.

Motives of Demand for Money:
According to Keynes, there are three motives for liquidity preferences. They are:

1. The Transaction Motive:
The transaction motive relates to the desire of the people to hold cash for the current transactions [or-day-to-day expenses] M = f(y)

2. The Precautionary Motive:

• The precautionary motive relates to the desire of the people to hold cash to meet unexpected or unforeseen expenditures such as sickness, accidents, fire, and theft.
• The amount saved for this motive also depends on the level of Income Mp = f(y).

3. The Speculative Motive:

• The speculative motive relates to the desire of the people to hold cash in order to take advantage of market movements regarding the future changes in the price of bonds and securities in the capital market. M = f(i)
• There is an inverse relation between liquidity preference and rate of interest.

Answer the following questions in a paragraph.

Question 1.
List out the Concepts of Profit?
Answer:
Concepts of Profit:

1. Gross Profit:
Gross Profit is the surplus that accrues to a firm when it subtracts its Total expenditure from its Total Revenue.
Gross Profit = Total Revenue – Total cost

2. Net profit or Pure Profit or Economic Profit or True Profit:
Net or pure or economic or true profit is the residual left with the entrepreneur after deducting from Gross profit The remuneration for the self-owned factors of production which are called implicit cost.
Net Profit = Gross Profit – implicit costs.

3. Normal Profit:
It refers to the minimum expected to return to stay in business

4. SuperNormal Profit:
Supernormal profits are over and above the normal profit.
SuperNormal Profit = Actual profit – Normal profit

Question 2.
Describe briefly the equilibrium between Demand and Supply of Money?
Answer:
1. The equilibrium between liquidity preference and demand for money determines the rate of interest.
2. In the short – run, the supply of money is assumed to be constant.

3. LP is the liquidity preference curve [demand curve.]

4. M₂M₂ shows the supply curve of money to satisfy speculative motives. Both curves intersect at point E, which is the equilibrium point. Hence, the rate of interest is 2.5. If liquidity preference increases from LP to L₁P₁ the supply of money remains constant, the rate of interest would increase from OI to OI_1.

5. Suppose LP remains constant. If the supply of money is OM₂, the interest is OI₂ and if the supply of money is reduced from OM₂ to OM₄, the interest would increase from OI₂ to OI₃. If the supply of money is increased from OM₂ to OM₄, the interest could decrease from OI₂ to OI₄.

Question 3.
Define the kinds of interest.
Answer:
Gross interest:
Gross interest is the total interest amount received by creditors from debtors.
Gross interest = Net interest + reward for inconvenience + insurance against the risk of non-repayment + payment for service of debt management.

Net interest:
Net interest is only a part of the gross interest. It is the payment for use of capital only. (Eg.) Interest payable for government securities.

PART – D

Answer the following questions on one page.

Question 1.
Explain the classical theory of Interest?
Answer:
The classical theory of Interest:

1. The equilibrium interest rate, according to classical theory, is determined by the intersection of demand and supply curves, Demand for money refers to investment.
2. The supply of money is referred to as savings. S = I.

Equilibrium:

1. The rate of interest is determined by the equilibrium between the total demand for and the total supply of loanable funds.
2. Supply of and Demand for Loanable funds:
3. Supply of loanable funds = Savings + Bank Credit + Dishoarding + Disinvestment = S + BC + DH + DI
4. Demand for loanable funds = Investment + consumption + Hoarding = I + C + H

• In Diagram X-axis represents the demand for and supply of loanable funds and the Y-axis represents the rate of interest.
• The LS curve represents the total supply curve of loanable funds.
• The summation of the Saving Curve [S], Bank credit curve [BC], Dishoarding curve [DH], and Disinvestment curve [DI],
• The LD curve represents the total demand for loanable funds.
• This is obtained by the summation of the demand for investment curve I, the demand curve for consumption demand or dissaving curve, and the curve for the demand for hoarding curve H.
• The LD and LS curves, intersect each other at the point “E” the equilibrium point.
• At this point, the OR rate of interest and OM is the number of loanable funds.

Question 2.
Illustrate the uncertainty Bearing Theory of profit?
Answer:
Uncertainty theory was propounded by the American economist Frank H.Knight. Profit is the reward for “ uncertainty bearing”. He distinguishes between “insurable” and “non-insurable” risks.

Insurable Risks:

1. Certain risks are measurable or calculable.
2. Some of the examples of these risks are the risk of fire, theft, and natural disasters.
3. Such risks are compensated by the Insurance companies.

Non-Insurable Risks:

1. There are some risks which are immeasurable or incalculable.
2. Examples of these risks are competition,, market condition, technology change, and public policy.
3. No Insurance Company can undertake these risks.
4. The term “risks” covers the first type of events (measurables-insurable)
5. The term “uncertainty” covers the second type of events (unforeseeable or incalculable or not measurable or non-insurable).
6. According to Knight, profit does not arise on account of risk-taking, because the entrepreneur can guard himself against risk by taking a suitable insurance policy.
7. Uncertain events cannot be guarded against in that way.
8. An entrepreneur takes himself the burden of facing an uncertain event, he secures remuneration.
9. That remuneration is “profit”.

Question 33.
State and explain the elasticity of supply?
Answer:

1. Elasticity of supply may be defined as the degree of responsiveness of change in supply to change in price on the part of sellers.
2. It is Mathematically expressed as,

Elasticity of supply = Proportionate change in supply/Proportionate change in price
e_s = \(\frac { \Delta Q_{ S } }{ Q_{ S } } \)/\(\frac { \Delta P }{ P } \)
e_s = \(\frac { \Delta Q_{ S } }{ \Delta P } \) × \(\frac{P}{Qs}\)
Where Q_s represents the supply, P presents price, ∆ denotes a change.

Question 34.
What are the functions of Entrepreneur?
Answer:
Functions of an Entrepreneur:
1. Initiation:
An organizer is the initiator of the business, by considering the situation and availability of resources and planning the entire process of business of production.

2. Innovation:
A successful entrepreneur is always an innovator. He introduces new methods in the production process.

3. Co – ordination:
An organizer applies a particular combination of the factor of production, to start and run the business or production.

4. Control, Direction and Supervision:

4. Time Wages:
Wages that are paid on the basis of the amount of time that the worker works.

Question 36.
Give short note on Cold Storage?

1. India is the largest producer of fruits and second largest producer of vegetables in the world.
2. Inspite of that per capita availability of fruits and vegetables is quite low because of post – harvest losses which account for about 25% to 30% of production.
3. Besides, quality of a sizable quantity of produce also deteriorates by the time it reaches the consumer.
4. Most of the problems relating to the marketing of fruits and vegetables can be traced to their perishability.
5. Perishability is responsible for high marketing costs, market gluts, price fluctuations and other similar problems.
6. In order to overcome this constraint, the Government of India and the Ministry of Agriculture promulgated an order known as “cold storage order, 1964” under section 3 of the Essential Commodities Act., 1955.

Question 37.
Compare positive economics and normative economics?
Answer:

Positive Economics	Normative Economics
1. An increase in money supply implies a price – rise is an economy.	1. Inflation is better than deflation.
2. As the irrigation facilities and application of chemical fertilizers expand, the production of food grains increases.	2. More production of luxury goods is not good for a less developed country.
3. An increase in the birth rate and a decrease in the death rate reflect the rate of growth of population.	Inequalities in the distribution of wealth and incomes should be reduced.

11. Erode is the main cloth market in South India for both retail and wholesale ready – mades.

Question 39.
What are the important features of utility?
Answer:
The important features of utility are:

1. Utility is psychological. It depends on the consumer’s mental attitude. For example, a vegetarian derives no utility from mutton.
2. Utility is not equivalent to usefulness. For example, a smoker derives utility from a cigarette; but, his health gets affected.
3. Utility is not the same a pleasure. A sick person derives utility from taking a medicine, but definitely it is not providing pleasure.
4. Utility is personal and relative. An individual obtains varied utility from one and the same good in different situations and places.
5. Utility is the function of the intensity of human want. An individual consumer faces a tendency of diminishing utility.
6. Utility cannot be measured objectively. It is a subjective concept and it cannot be measured numerically.
7. Utility has no ethical or moral significance. For example, a cook derives utility from a knife using which he cuts some vegetables, and a killer wants to stab his enemy by that knife. In economics, a commodity has utility if it satisfies a human want.

Question 40.
Mention the features of SHGs?

Answer all the questions. [7 × 5 = 35]

Question 41 (a).
A firm has the revenue function R = 600q – 0.03q² and the cost function is
C = 150q + 60,000, where q is the number of units produced. Find AR, AC, MR and MC?
Answer:
(I) Average Revenue = \(\frac{R}{q}\)
\(\frac { 600q-0.03q^{ 2 } }{ q } \) = \(\frac{600q}{q}\) – \(\frac { 0.03q^{ 2 } }{ q } \)
AR = 600 – 0.03q

(II) Average Cost = \(\frac{C}{q}\)
= \(\frac{150q+60000}{q}\)
= \(\frac{150q}{q}\) + \(\frac{60000}{q}\)
AC = 150 + \(\frac{60000}{q}\)

(III) Marginal Revenue = \(\frac{dR}{dq}\)
R = 600q – 0.03q²
\(\frac{dR}{dq}\) = 600 – (0.03)q²
\(\frac{dR}{dq}\) = 600 – (0.03)(2q)
MR = 600 – 0.06q

(IV) Marginal Cost = \(\frac{dC}{dq}\)
C = 150q + 60000
MC = 50

Question 42 (a).
Illustrate the concept of producer’s equilibrium?
Answer:
Producer equilibrium implies the situation where producer maximizes his output. It is also known as optimum combination of the factors of production. In short, the producer manufactures a given amount of output with ‘least cost combination of factors’, with his given budget.

Optimum Combination of Factors implies either:
There is output maximisation for given inputs or there is cost minimisation for the given output.

Conditions for Producer Equilibrium:
The two conditions that are to be fulfilled for the attainment of producer equilibrium are:
The iso – cost line must be tangent to iso – quant curve. At point of tangency, the iso-quant curve must be convex to the origin or MRTSLk must be declining.

2. When AC becomes constant, MC also becomes equal to it.
3. When AC starts increasing, MC lies above the AC.
4. MC curve always cuts AC at its minimum point from below.

Question 43 (a).
Explain various divisions of Economics?
Answer:
Economics sub divisions are:

(I) Consumption:

• Human wants coming under consumption is the starting point of economic activity.
• In this section the characteristics of human wants based on the behaviour of the consumer, the diminishing marginal utility and consumer’s surplus are dealt with.

(II) Production:

• Production is the process of transformation of inputs into output.
• This division covers the characteristics and role of the factors of production namely land, labour, capital and organization.

(III) Exchange:

• Exchange is concerned with price determination in different market forms.
• This division covers trade and commerce.
• Consumption is possible only if the produced commodity is placed in the hands of the consumer.

(IV) Distribution:

• Production is the result of the coordination of factors of production.
• Since a commodity is produced with the efforts of land, labour, capital and organization, the produced wealth has to be distributed among the cooperating factors.
• The reward for factors of production is studied in this division under rent, wages, interest and profit.
• Distribution studies about the pricing of factors of production.

[OR]

(b) Explain the law of demand and its exceptions?
Answer:
Definitions:
The Law of Demand says as “the quantity demanded increases with a fall in price and diminishes with a rise in price”. – Marshall
“The Law of Demand states that people will buy more at lower price and buy less at ‘ higher prices, other things remaining the same”. – Samuelson

Assumptions of Law of Demand:

1. The income of the consumer remains constant.
2. The taste, habit and preference of the consumer remain the same.
3. The prices of other related goods should not change.
4. There should be no substitutes for the commodity in study.
5. The demand for the commodity must be continuous.
6. There should not be any change in the quality of the commodity.

Given these assumptions, the law of demand operates. If there is change even in one of these assumptions, the law will not operate.

Explanation:
The law of demand explains the relationship between the price of a commodity and the quantity demanded of it. This law states that quantity demanded of a commodity expands with a fall in price and contracts with a rise in price.

In other words, a rise in price of a commodity is followed by a contraction demand and a fall in price is followed by extension in demand. Therefore, the law of demand states that there is an inverse relationship between the price and the quantity demanded of a commodity.

Exceptions to the law of demand:
Normally, the demand curve slopes downwards from left to right. But there are some unusual demand curves which do not obey the law and the reverse occurs. A fall in price brings about a contraction of demand and a rise in price results in an extension of demand. Therefore the demand curve slopes upwards from left to right.

It is known as exceptional demand curve. In the above diagram, DD is the demand curve which slopes upwards from left to right. It shows that when price is OP₁, OQ₁, is the demand and when the price rises to OP₂, demand also extends to OQ₂.

Question 44 (a).
How price and output are determined under the perfect competition?
Answer:
Perfect Competition: Firm’s Equilibrium in the Short Run

In the short run, at least a few factors of production are fixed. The firms under Perfect Competition take the price (10) from the industry and start adjusting their quantities produced. For example Q_d = 100 – 5P and Q_s = 5P.

At equilibrium Q_d = Q_s
Therefore 100 – 5P = 5P
100 = 10P; 100/10 = P; Qd = demand
P = 10; P = Price
Qd = 100 – 5(10); Q_s = Supply
100 – 50 = 50
Q_s = 5 (10) = 50
Therefore 50 = 50

This diagram consists of three panels. The equilibrium of an industry is explained in the first panel. The demand and supply forces of all the firms interact and the price is fixed as 10. The equilibrium of an industry is obtained at 50 units of output.

In the second part of the diagram, AC curve is lower than the price line. The equilibrium condition is achieved where MC = MR. Its equilibrium quantity sold is 50. With the prevailing price, ₹ 10 it experiences super normal profit. AC = ₹ 8, AR = ₹ 10.

Its total revenue is 50 × 10 = 500. Its total cost is 50 × 8 = 400. Therefore, its total profit is 500 – 400 = 100.

In the third part of the diagram, firm’s cost curve is above the price line. The equilibrium condition is achieved at point where MR = MC. Its quantity sold is 50. With the prevailing price, it experiences loss. (AC > AR). Its total revenue is 50 × 10 = 500. Its total cost is 50 × 12 = 600. Therefore, its total loss is 600 – 500 = 100.

As profit prevails in the market, new firms will enter the industry, thus increasing the supply of the product. This means a decline in the price of the product and increase the cost of production. Thus, the abnormal profit will be wiped out; loss will be incurved. When loss prevails in the market, the existing loss making firms will exit the industry, thus decreasing the supply of the product.

This means a rise in the price of the product and reduction in the cost of production. So the loss will vanish; Profit will emerge. Consequent upon the entry and exit of new firms into the industry, firms always earn ‘normal profit’ in the long run as shown in diagram.

(b) Elucidate the Loanable funds Theory of Interest?
Answer:

1. The Loanable Funds Theory, also known as the “Neo – Classical Theory,” was developed by Swedish economists like Wicksell, Bertil, Ohlin, Viner, Gunnar Myrdal and others.
2. According to this theory, interest is the price paid for the use of loanable funds.
3. The rate of interest is determined by the equilibrium between demand for and supply of ‘ loanable funds in the credit market.

Demand for loanable funds
The demand for loanable funds depends upon the following:

(I) Demand for Investment [I]

• The most important factor responsible for the loanable funds is the demand for investment.
• Bulk of the demand for loanable funds comes from business firms which borrow money for purchasing capital goods.

(II) Demand for consumption [C]
The demand for loanable funds comes from individuals who borrow money for consumption purposes also.

(III) Demand for Hoarding [H]

• The next demand for loanable funds comes from hoarders. Demand for hoarding money arises because of people’s preference for liquidity, idle cash balances and so on.
• The demand for C, I and H varies inversely with interest rate.

Supply of Loanable funds:
The supply of loanable funds depends upon the following four sources:

1. Savings [S]:
Loanable funds comes from savings. According to this theory, savings may be of two types, namely,

• Savings planned by individuals are called “ex-ante-savings ”.
• The unplanned savings are called ‘ex-post savings”.

2. Bank Credit [BC]:
The bank credit is another source of loanable funds. Commercial banks create credit and supply loanable funds to the investors.

3. Dishoarding [DH]:
Dishoarding means bringing out the hoarded money into use and thus it constitutes a source of supply of loanable funds.

4. Disinvestment: [DI]:
Disinvestment is the opposite of investment. Disinvestment means not providing sufficient funds for depreciation of equipment.

It gives rise to the supply of loanable funds. All the four sources of supply of loanable funds vary directly with the interest rate.

Question 45 (a).
The features of Rural Economy are peculiar’Argue?
Answer:
Features of Rural Economy:

(I) Village is an Institution:
The village is a Primary Institution and it satisfies almost all the needs of the rural community. The rural people have a feeling of belongingness and a sense of unity towards each other.

Dependence on Agriculture:
The rural economy depends much on nature and agricultural activities. Agriculture and allied activities are the main occupation in rural areas.

Life of Rural people:
Lifestyles in villages are very simple. Public services like education, housing, health and sanitation, transport and communication, banking, roads and markets are limited and unavailable.

The standards of living of majority of rural people are poor and pitiable. In terms of methods of production, social organization and political mobilization, rural sector is extremely backward and weak.

Population Density:
Population density, measured by number of persons living per sq.km is very low and houses are scattered in the entire villages.

Employment:
There exists unemployment, seasonal unemployment and under employment in rural areas.

Poverty:
Poverty is a condition where the basic needs of the people like food, clothing and shelter are not being met.

Indebtedness:
People in rural areas are highly indebted owing to poverty and underemployment, lack of farm and non – farm employment opportunities, low wage employment, seasonality in production, poor marketing network etc.

Rural Income:
The Income of the rural people is constrained as the rural economy is not sufficiently vibrant to provide them.

Dependency:
Rural households are largely dependent on social grants and remittances from family members working in urban areas and cities.

Dualism:
Dualism means the co-existence of two extremely different features like developed and under developed. These characteristics are very common in rural areas. Inequality: The distributions of income, wealth and assets are highly skewed among rural people. Land, livestock and other assets are owned by a few people.

Migration:
Rural people are forced to migrate from villages to urban areas in order to seek gainful employment for their livelihood.

Question 46 (a).
What are the methods of measuring Elasticity of demand?
Answer:
There are three methods of measuring price elasticity of demand.

1. The Percentage method:
e_p = \(\frac { \Delta Q }{ \Delta P } \), \(\frac{P}{Q}\)
It is also known as ratio method, when we measure the ratio as:
e_p = \(\frac { %\Delta Q }{ %\Delta P } \) where,
% ∆Q = Percentage change in demand
% ∆P = Percentage change in price

2. Total Outlay Method:
Marshall suggested that the simplest way to decide whether demand is elastic or inelastic is to examine the change in total outlay of the consumer or total revenue of the firm Total Revenue = (Price × Quantity Sold)
TR = ( P × Q)

Where there is inverse relation between Price and Total Outlay, demand is elastic. Direct relation means inelastic. Elasticity is unity when Total Outlay is constant.

3. Point or Geometrical Elasticity:
When the demand curve is a straight line, it is said to be linear. Graphically, the point elasticity of a linear demand curve is shown by the ratio of the segments of the line to the right and to the left of the particular point.
Lower segment of the demand curve
Point Elasticity =

e_p = \(\frac{L}{U}\)
Where ‘e_p’ stands for point elasticity, ‘L’ stands for the lower segment and ‘U’ for the upper segment.

(b) Explain the VKRV Rao’s National Income Methodology and Industrialization?
Answer:
(a) Rao’s National Income Methodology:

1. Rao’s name is remembered for his pioneering work on the enumeration of national income of India.
2. He attempted
   • To develop the national income concepts suited to India and developing countries.
   • To analyze the concepts of investment, saving and the multipliers is an underdeveloped economy.
   • To study the compatibility of the national incomes of Industrialized and underdeveloped countries.
3. Rao’s paper on “Full Employment and Economic Development” was one of the earliest contributions in the field of development towards employment.

(b) Rao’s views on Industrialization:
Rao gave the following reasons for low per capita income and low levels of per capita nutrition in India.

1. Uneconomic holdings with sub-divisions and fragmentation.
2. Low levels of water availability for crops.
3. Excess population pressure on agriculture due to the absence of a large industrial sector.
4. Absence of capital.
5. Absence of autonomy in currency policy, and in general in monetary matters encouraging holding of gold.

Question 47 (a).
Compare and contrast various definitions of economics?
Answer:
1. Adam Smith’s wealth definition:

• Adam Smith [1723 – 1790] in his book “An Inquiry into Nature and Cause of Wealth of Nations” [1776] defines “Economics as the science of wealth”
• He explains how a nation’s wealth is created and increased.
• He considers that the individual in the society wants to promote his own gain and in this process, he is guided and led by an “invisible hand”
• Adam Smith favours the introduction of “division of labour” to increase the quantum of output.
• Severe competition in factories and society helps in bettering the product.
• Supply force is very active and a commodity is made available to the consumers at the lowest price.

2. Alfred Marshall welfare definition: .

• Alfred Marshall [1842-1924] in his book “Principles of Economics” [1890] defines economics thus “Political Economy” or Economics is a study of mankind in the ordinary business of life.
• It examines that part of individual and social action which is most closely connected with the attainment and with the use of the material requisites of well being.
• Thus , it is on one side a study of wealth and on the other and more important side, a part of the study of man”.

The important features of Marshall’s definition are:

• Economics does not treat wealth as’the be-all and end-all of economic activities.
• Man promotes primarily welfare and not wealth.
• The science of economics contains the concerns of ordinary people who are moved by love and not merely guided or directed by the desire to get maximum monetary benefit.
• Economics is a social science. It studies people in the society who influence one another.

3. Lionel Robbins – Scarcity definition:

• Lionel Robbins published a book “An Essay on the Nature and Significance of Economic Science” in 1932.
• According to him, “Economics is a science which studies human behaviour as a relationship between ends and scarce means which have alternative uses”.

The major features of Robbins’ definition:

• Ends refer to human wants, human beings have unlimited number of wants.
• On the other hand, resources or means that go to satisfy the unlimited human wants are limited or scarce in supply.
• The scarce means are capable of having alternative uses.
• An individual grades his wants and satisfies first his most urgent want.
• Economics, according to Robbins, is a science of choice. •

4. Samuelson’s – growth definition:

• Paul Samuelson defines economics as “the study of how men and society choose, with or without the use of money, to employ scarce productive resources which could have alternative uses to produce various. commodities over time, and distribute them for consumption, now and in the future among various people and groups of society”.
  The major implications of this definition are as follows:
• Samuelson’s makes his definition dynamic by including the element of time in it.
• Samuelson’s definition is applicable also in a barter economy.
• His definition covers various aspects like production, distribution and consumption.
• Samuelson treats economics as a social science.
• Samuelson appears to be the most satisfactory.

(b) Explain the law of Equi – marginal utility?
Answer:
The law of the Equi-marginal utility:

1. The law of diminishing marginal utility is applicable only to the want of a single commodity.
2. The law of equi – marginal utility explains the behavior of a consumer when he consumer more than one commodity.
3. Wants are unlimited but the income which is available are limited.
4. This law explains how the consumer spends his limited income on various commodities to get maximum satisfaction.
5. Law of Equi-Marginal Utility is also known as the law of substitution.
6. “The law of consumer’s equilibrium ”
7. “Gossen’s second law ” and “ The law of maximum satisfaction”.

Definition:
Marshall states the law as, “If a person has a thing which he can put to several uses, he will distribute it among these uses in such a way that it has the same marginal utility in all. For, if it had a greater marginal utility in one use than another he would gain by taking away some of it from the second use and applying it to first”.

Assumption:

1. The consumer is rational in the sense that he wants to get maximum satisfaction.
2. The utility of each commodity is measurable in cardinal numbers.
3. The marginal utility of money remains constant.
4. The income of the consumer is given. ‘
5. There is perfect competition in the market.
6. The prices of the commodities are given.
7. The law of diminishing marginal utility operates.

Illustration:
This law can be illustrated with the help of table. Let us assume that the consumer has a given income of ₹ 11. He wants to spend this entire income [i.e. ₹ 11] on Apple and Orange. The price of an Apple and the price of an orange is ₹ 1 each.

If the consumer wants to attain maximum utility, he should buy 6 units of apples and 5 units of oranges, so that she can get [92 + 58] = 150 units. No other combination of Apple and Orange can give higher than 150 utilities.

Diagrammatic Illustration:
In the diagram, X – axis represents the amount of money spent and Y axis represents the marginal utilities of Apple and Orange respectively.

If the consumer spends ₹ 6 on Apple and ₹ 5 on Orange, the marginal utilities of both are equal, i.e. AA₁ = BB₁ [4 = 4], Hence, he gets maximum utility.

Criticisms:

1. In practice, utility cannot be measured, only be felt.
2. This law cannot be applied to durable goods.

Question 35.
What are the motives of demand for money?
Answer:
Motives of Demand for Money:
According to Keynes, there are three motives for liquidity preference. They are:

1. The Transaction Motive :

• The transaction motive relates to the desire of the people to hold cash for the current transactions.
• The amount saved under this motive depends on the level of income. M_t = f(y)

2. The Precautionary Motive:

• The precautionary motive relates to the desire of the people to hold cash to meet unexpected or unforeseen expenditures such as sickness, accidents, fire and theft.
• The amount saved for this motive also depends on the level of income. M_p – f(r)

3. The Speculative Motive:
The speculative motive relates to the desire of the people to hold cash in order to take advantage of market movements regarding the future changes in the price of bonds and securities in the capital market. The amount saved for this motive depends on the rate of interest.

M_S = f(i). There is inverse relation between liquidity preference and rate of interest.

Question 36.
State Ambedkar’s Economic Ideas on agricultural economics?
Answer:
In the 1918, Ambedkar published a paper “Small Holding in India and their Remedies”. Citing Adam Smith’s “Wealth of Nations”, he made a fine distinction between “Consolidation of Holdings” and Enlargement of Holdings”.

Question 37.
What are the functions of Entrepreneur?
Answer:
Functions of an Entrepreneur:

1. Initiation: An organizer is the initiator of the business, by considering the situation and availability of resources and planning the entire process of business of production.
2. Innovation: A successful entrepreneur is always an innovator. He introduces new methods in the production process.
3. Co – ordination: An organizer applies a particular combination of the factor of production to start and run the business or production.
4. Control, Direction and Supervision: An organiser controls so that nothing prevents the organisation from achieving its goal. He directs the factors to get better results and supervises for the efficient functioning of all the factors involved in the process of production.
5. Risk – taking and uncertainty – bearing: There are risk – taking and uncertainty-bearing obstacles. Risks may be insured but uncertainties cannot be insured. They reduce the profit.

Question 38.
Explain GSDP in Tamil Nadu?
Answer:

1. The Gross State Domestic Product (GSDP) refers to the total money value of all the goods and services produced annually in the state.
2. Tamil nadu is the second largest economy in India with a GSDP of $ 207.8 billion in 2016 – 2017 according to the Directorate of Economics and Statistics, Tamil Nadu.
3. The GSDP of Tamil Nadu is equal to the GDP of Kuwait on nominal term and GDP of UAE on PPP terms. Per capita GSDP would be better for intercountry or interstate comparisons.
4. Tamil Nadu GSDP = $207.8 billion in 2016 – 17.

Question 39.
Briefly explain the concept of consumer’s equilibrium?
Answer:
The consumer reaches equilibrium at the point where the budget line is tangent on the indifference curve. T is the point of equilibrium as budget line AB is tangent on indifference curve IC3 the upper IC which implies maximum possible level of satisfaction.

At equilibrium point, the slope of IC refers to MRS_XY and the slope of BL (Budget Line) refers to ratio of price of X to price of Y i.e. P_x / P_y . Therefore MRS_x,y = P_x / P_y.

Question 40.
List out the kinds of wages:
Answer:
Wages are divided into four types.

1. Nominal Wages or Money Wages: Nominal wages are referred to the wages paid in terms of money.
2. Real Wages: Real wages are the wages paid in terms of goods and services. Hence, real wages are the purchasing power of money wages.
3. Piece Wages: Wages that are paid on the basis of quantum of work done.
4. Time Wages: Wages that are paid on the basis of the amount of time that the worker works.

Question 41 (a).
Write a brief note on the Gandhian economic ideas?
Answer:
Gandhian Economics is based on ethical foundations. Gandhi wrote “ Economics that hurts the moral well-being of an individual or a nation is immoral, and therefore , Sinful”. Gandhi repeated the same belief “ that economy is untrue which ignores or disregards moral values”.

Salient features of Gandhian Economic Thought:

(I) Village Republics:

• India lives in villages.
• He was interested in developing the villages as self – sufficient units.
• He opposed extensive use of machinery, urbanization and industrialization.

(II) On Machinery:

• Gandhi described machinery as ‘Great sin’. He said that “Books could be written to demonstrate its evils”.
• It is necessary to realize that machinery is bad.
• Instead of welcoming machinery as a boon, we should look upon it as an evil.
• It would ultimately cease.

(III) Industrialism:

• Gandhi considered industrialism as a curse on mankind.
• He thought industrialism depended entirely on a country’s capacity to exploit.

(IV) Decentralization:
Gandhi advocated a decentralized economy i. e., production at a large number of places on a small scale or production in the people’s homes.

(V) Village Sarvodaya:

• According to Gandhi, “ Real India was to be found in villages and not in towns or cities”.
• He suggested, self – dependent villages.

(VI) Bread Labour:

• Gandhi realized the dignity of human labour.
• He believed that God created man to eat his bread by the sweat of his brow.
• Bread labour or body labour was the expression that Gandhi used to mean manual labour.

(VII) The Doctrine of Trusteeship:
Trusteeship provides a means of transforming the present capitalist order of society into an egalitarian one.

(VIII) On the Food Problem:

• Gandhi was against any sort of food controls.
• Once India was begging for food grain, but now India tops the world with very large production of food grains, fruits, vegetables, milk, egg, meat etc.

(IX) On Population:

• Gandhi opposed the method of population control through contraceptives.
• He was, however, in favour of birth control through Brahmacharya or self – control.
• He considered self – control as a sovereign remedy to the problem of Over population.

(X) On Prohibition:

• Gandhi regarded the use of liquor as a disease rather than a vice.
• He felt that it was better for India to be poor than to have thousands of drunkards.
• Many states depend on revenue from liquor sales.

[OR]

(b) Analyse the causes for Rural Indebtedness?
Answer:
The Causes for Rural Indebtedness:

(I) Poverty of Farmers:

• The vicious circle of poverty forces the farmers to borrow for consumption and cultivation.
• Thus poverty, debt and high rates of interest hold the farmer in the grip of money lenders.

(II) Failure of Monsoon:

• Frequent failure of monsoon is a curse to the farmers and they have to suffer due to the failure of nature.
• Farmers find it difficult to identify good years to repay their debts.

(III) Litigation:

• Due to land disputes litigation in the court compels them to borrow heavily.
• Being uneducated and ignorant they are caught in the litigation process and dry away their savings and resources.

(IV) Money Lenders and High Rate of Interest:
The rate of interest charged by the local money lenders is very high and the compounding of interest leads to perpetuate indebtedness of the farmer.

Question 42 (a).
Explain various divisions of Economics?
Answer:
Economics sub divisions are:

(I) Consumption:

• Human wants coming under consumption is the starting point of economic activity.
• In this section the characteristics of human wants based on the behaviour of the consumer, the diminishing marginal utility and consumer’s surplus are dealt with.

(II) Production:

• Production is the process of transformation of inputs into output.
• This division covers the characteristics and role of the factors of production namely land, labour, capital and organization.

(III) Exchange:

• Exchange is concerned with price determination in different market forms.
• This division covers trade and commerce.
• Consumption is possible only if the produced commodity is placed in the hands of the consumer.

(IV) Distribution:

• Production is the result of the coordination of factors of production.
• Since a commodity is produced with the efforts of land, labour, capital and organization, the produced wealth has to be distributed among the cooperating factors.
• The reward for factors of production is studied in this division under rent, wages, interest and profit.
• Distribution studies about the pricing of factors of production.

(b) Explain the law of demand and its exceptions?
Answer:
Definitions:
The Law of Demand says as “the quantity demanded increases with a fall in price and diminishes with a rise in price”. – Marshall
“The Law of Demand states that people will buy more at lower price and buy less at higher prices, other things remaining the same”. – Samuelson Assumptions of Law of Demand:

1. The income of the consumer remains constant.
2. The taste, habit and preference of the consumer remain the same.
3. The prices of other related goods should not change.
4. There should be no substitutes for the commodity in study.
5. The demand for the commodity must be continuous.
6. There should not be any change in the quality of the commodity.

Given these assumptions, the law of demand operates. If there is change even in one of these assumptions, the law will not operate.

Explanation:
The law of demand explains the relationship between the price of a commodity and the quantity demanded of it. This law states that quantity demanded of a commodity expands with a fall in price and contracts with a rise in price.

In other words, a rise in price of a commodity is followed by a contraction demand and a fall in price is followed by extension in demand. Therefore, the law of demand states that there is an inverse relationship between the price and the quantity demanded of a commodity.

Exceptions to the law of demand:
Normally, the demand curve slopes downwards from left to right. But there are some unusual demand curves which do not obey the law and the reverse occurs.

A fall in price brings about a contraction of demand and a rise in price results in an extension of demand. Therefore the demand curve slopes upwards from left to right. It is known as exceptional demand curve.

In the above diagram, DD is the demand curve which slopes upwards from left to right. It shows that when price is OP₁,, OQ₁, is the demand and when the price rises to OP₂, demand also extends to OQ₂.

Question 43 (a).
Describe the degree of price discrimination?
Answer:
Degrees of Price Discrimination:
Price discrimination has become widespread in almost all monopoly markets. According to A.C.Pigou, there are three degrees of price discrimination.

(I) First degree price discrimination:
A monopolist charges the maximum price that a buyer is willing to pay. This is called as perfect price discrimination. This price wipes out the entire consumer’s surplus. This is maximum exploitation of consumers. Joan Robinson named it as “Perfect Discriminating Monopoly”.

(II) Second degree price discrimination:
Under this degree, buyers are charged prices in such a way that a part of their consumer’s surplus is taken away by the sellers. This is called as imperfect price discrimination. Joan Robinson named it as “Imperfect Discriminating Monopoly”.

Under this degree, buyers are divided into different groups and a different price is charged for each group. For example, in cinema theatres, prices are charged for same film show from viewers of different classes. In a theatre the difference between the first row of first class and the last row in the second class is smaller as compared to the differences in charges.

(III) Third degree price discrimination:
The monopolist splits the entire market into a few sub – market and charges different price in each sub – market. The groups are divided on the basis of age, sex and location. For example, railways charge lower fares from senior citizens. Students get discounts in museums, and exhibitions.

(b) Write a short note on Total Revenue?
Answer:
Total revenue is the amount of income received by the firm from the sale of its products. It is obtained by multiplying the price of the commodity by the number of units sold.

where, TR denotes Total Revenue, P denotes Price and Q denotes Quantity sold.
For example, a cell – phone company sold 100 cell – phones at the price of ₹500 each.
TR is ₹50,000. (TR = 500 × 100 = 50,000).

When price is constant, the behaviour of TR is shown in the above table and diagram, assuming P = 5. When P = 5; TR = PQ

When price is declining with increase in quantity sold. (Eg. Imperfect Competition on the goods market) the behaviour of TR is shown in the following table and diagram. TR can be obtained from Demand fuction: If Q = 11 – P,
When P = 1, Q = 10

TR = PQ = 1 × 10 = 10
When P = 3, Q = 8, TR = 24
When P = 0, Q = 1, TR = 10

[OR]

(b) Mention the causes for Rural poverty?
Answer:
Causes for Rural Poverty:
1. Unequal distribution of Land:
The distribution of land is highly skewed in rural areas. Therefore, majority of rural people work as hired labour to support their families.

2. Lack of Non – Farm Employment:
Non – farm employment opportunities do not match the increasing labour force. The excess supply of labour in rural areas reduces the wages and increases the incidence of poverty.

3. Lack of public sector Investment:
The root cause of rural poverty in our country is lack of public sector investment on human resource development.

4. Inflation:
Steady increase in prices affects the purchasing power of the rural poor leading to rural poverty.

5. Low productivity:
Low productivity of rural labour and farm activities is a cause as well as the effect of poverty.

6. Unequal Benefit of Growth:
Major gains of economic development are enjoyed by the urban rich people leading to concentration of wealth. Due to defective economic structure and policies, gains of growth are not reaching the poor and the contributions of poor people are not accounted properly.

7. Low Rate of Economic Growth:
The rate of growth of India is always below the target and it has benefited the rich. The poor are always denied of the benefits of the achieved growth and development of the country.

8. More Emphasis on Large Industries:
Huge investment in large industries catering to the needs of middle and upper classes in urban areas are made in India. Such industries are capital-intensive and do not generate more employment opportunities. Therefore, poor are not in a position to get employed and to come out from the poverty in villages.

9. Social evils:
Social evils prevalent in the society like custom, beliefs, etc., increase unproductive expenditure.

Question 45 (a).
Bring out the relationship between TR, AR, MR and Elasticity of demand?
Answer:
Relationship among TR, AR and MR Curves:
When marginal revenue is positive, total revenue rises, when MR is zero the total revenue becomes maximum. When marginal revenue becomes negative total revenue starts falling. When AR and MR both are falling, then MR falls at a faster rate than AR.

TR, AR, MR and Elasticity of demand:

1. The relationship among AR, MR and elasticity of demand (e) is stated as follows.
   MR = AR (e – 1/e)
2. The relationship between The AR curve and MR curve depends upon the elasticity of AR curve [AR = DD = Price]

• When price elasticity of demand is greater than one, MR is positive and TR is increasing.
• When price elasticity of demand is less than one, MR is negative and TR is decreasing.
• When price elasticity of demand is equal to one, MR is equal to Zero and TR is maximum and constant.

It is to be noted that, the output range of 1 to 5 units, the price elasticity of demand is greater than one according to total outlay method. Hence, TR is increasing and MR is positive.
TR, AR, MR & Elasticity

At the output range of 5 to 6 units, the price elasticity of demand is equal to one. Hence, TR is maximum and MR is equals to zero. At the output range of 6 units to 10 units, the price elasticity of demand is less than unity. Hence, TR is decreasing and MR is negative.

(b) Explain the monetary and financial sector reforms?
Answer:
Monetary reforms aimed at doing away with interest rate distortions and rationalizing the structure of lending rates. The new policy tried in many ways to make the banking system more efficient. Some of the measures undertaken were:

(I) Reserve Requirements:

• Reduction in Statutory liquidity ratio [SLR] and the cash reserve ratio [CRR] were the recommendations by the Narasimham Committee Report, 1991.
• It was proposed to cut down the SLR from 38.5 percent to 25 percent within a time span of three years.

(II) Interest Rate Liberalisation:
RBI controlled:

• The interest rates payable on deposits. The interest rate which could be charged for bank loans.
• Greater competition among public sector, private sector and foreign banks and elimination of administrative constraints.
• Liberalisation of bank branch licensing policy in order to rationalize the existing branch network.
• Banks were given freedom to relocate branches and open specialized branches.
• Guidelines for opening new private sector banks.
• New accounting norms regarding classification of. assets and provisions of bad debt were introduced in tune with the Narasimham Committee Report.

Question 46 (a).
Examine the law of variable proportions with the help of a diagram?
Answer:
The law states that if all other factors are fixed and one input is varied in the short run, the total output will increase at an increasing rate at first instance^ be constant at a point and then eventually decrease. Marginal product will become negative at last.

According to G.Stigler, “As equal increments of one input are added, the inputs of other productive services being held constant, beyond a certain point, the resulting increments of product will decrease, i.e., the marginal product will diminish”.

Assumptions:
The Law of Variable Proportions is based on the following assumptions.

• Only one factor is variable while others are held constant.
• All units of the variable factor are homogeneous.
• The product is measured in physical units.
• There is no change in the state of technology.
• There is no change in the price of the product.

Total Product (TP)
Total product refers to the total amount of commodity produced by the combination of all inputs in a given period of time.

Summation of marginal products, i.e.
TP = ΣMP
where, TP = Total Product,
MP = Marginal Product

Average Product (AP)
Average Product is the result of the total product divided by the total units of the input employed. In other words, it refers to the output per unit of the input.
Mathematically, AP = TP/N
Where, AP = Average Product
TP = Total Product
N = Total units of inputs employed

Marginal Product (MP)
Marginal Product is the addition or the increment made to the total product when one more unit of the variable input is employed. In other words, it is the ratio of the change in the total product to the change in the units of the input. It is expressed as
MP = ∆TP/∆N

where,
MP = Marginal Product
∆TP = Change in total product
∆N = Change in units of input It is also expressed as
MP = TP(n) – TP (n – 1)
Where, MP = Marginal Product
TP(n) = Total product of employing n^th unit of a factor.
TP(n – 1) = Total product of employing the previous unit of a factor, that is, (n – 1)^th unit of a factor.
The Law of Variable Proportions is explained with the help of the following schedule and diagram:

In above table, units of variable factor (labour) are employed along with other fixed factors of production. The table illustrates that there are three stages of production. Though total product increases steadily at first instant, constant at the maximum point and then diminishes, it is always positive forever.

While total product increases, marginal product increases up to a point and then decreases. Total product increases up to the point where the marginal product is zero. When total product tends to diminish marginal product becomes negative.

In diagram, the number of workers is measured on X axis while TP_L, AP_L and MP_L are denoted on Y axis. The diagram explains the three stages of production as given in the above table.

Stage I:
In the first stage MP_L increases up to third labourer and it is higher than the average product, so that total product is increasing at an increasing rate. The tendency of total product to increase at an increasing rate stops at the point A and it begins to increase at a decreasing rate. This point is known as ‘Point of Inflexion’.

Stage II:
In the second stage, MP_L decreases up to sixth unit of labour where MP_L curve intersects the X – axis. At fourth unit of labor MP_L = AP_L. After this, MP_L curve is lower than the AP_L. TP_L increases at a decreasing rate.

Stage III:
Third stage of production shows that the sixth unit of labour is marked by negative MP_L, the AP_L continues to fall but remains positive. After the sixth unit, TP_L declines with the employment of more units of variable factor, labour.

[OR]

(b) What are the types of elasticity of supply?
Answer:
There are five types of elasticity of supply

1. Relatively Elastic Supply:
The co – efficient of elastic supply is greater than 1 [E_S > 1], One percent change in the price of a commodity causes more than one percent change in the quantity supplied of the commodity.

2. Unitary Elastic Supply:
The co – efficient of elastic supply is equal to 1 [E_g = 1]. One percent change in the price of a commodity causes an equal [one percent ] change in the quantity supplied of the commodity.

3. Relatively Inelastic Supply:
The co-efficient of elasticity is less than one [ES < 1]. One percent change in the price of a commodity causes and less than one percent change in the quantity supply supplied of the commodity.

4. Perfectly Inelastic Supply:
The co – efficient of elasticity is equal to zero [E_S = 0], One percent change in the price of a commodity causes no change in the quantity supplied of the commodity.

5. Perfectly Elastic Supply:
The co – efficient of elasticity of supply is infinity [E_S = 3]. One percent change in the price of a commodity causes an infinite change in the quantity supplied of the commodity.

Question 1.
If P (A) = \(\frac{2}{3}\), P(B) = \(\frac{2}{5}\), P(A ∪ B) = \(\frac{1}{3}\), then find P(A ∩ B).
Answer:
P(A ∪ B) = P (A) + P (B) – P (A ∩ B)
\(\frac{1}{3}=\frac{2}{3}+\frac{2}{5}\) – P (A ∩ B)

Question 2.
A and B are two events such that, P(A) = 0.42, P(B) = 0.48, and P(A∩B)=016. Find (i) P(not A)
(ii) P(not B)
(iii) P(A or B)
Solution:
(a) P(A) = 0.42 ;
P(B) = 0.48
P(A∩B) = 0.16
(i) P(not A) = P(\(\overline{\mathbf{A}}\)) = 1 – P(A) = 1 – 0.42 = 0.58
(ii) P(not B) = P(\(\overline{\mathbf{B}}\)) = 1 – P(B) = 1 – 0.48 = 0.52
(iii) P(A or B) = P(A∪B) = P(A) + P(B) – P(A∩B)
= 0.42 + 0.48 – 0.16
= 0.74

Question 3.
If A and B are two mutually exclusive events of a random experiment and P (not A) = 0.45, P (A ∪ B) = 0.65, then find P(B).
Answer:
P(not A) = 0.45
1 – P (A) = 0.45
P (A) = 1 – 0.45 = 0.55
P(A ∪ B) = P (A) + P (B)
0. 65 = 0.55 + P(B)
0. 65 – 0.55 = P(B)
0.10 = P (B)
P(B) = 0.1

Question 4.
The probability that atleast one of A and B occur is 0.6. If A and B occur simultaneously with probability 0.2, then find P(\(\overline{\mathbf{A}}\)) + P(\(\overline{\mathbf{B}}\)).
Solution:
P(A∪B) = 0.6
P(A∩B) = 0.2
P(A) + P(B) = [1 – P(A∪B)] + [1 – P(A∩B)] = [1 – 0.6] + [1 – 0.2]
= 0.4 + 0.8 = 1.2

Question 5.
The probability of happening of an event A is 0.5 and that of B is 0.3. If A and B are mutually exclusive events, then find the probability of neither A nor B happen.
Answer:
Here P(A) = 0.5, P (B) = 0.3
P(A ∪ B) = P (A) + P(B) [A and B are mutually exclusive]
= 0.5 + 0.3
= 0.8
Probability of neither A nor [P(A ∪ B)’] = 1 – P(A ∪ B) = 1 – 0.8 = 0.2

Question 6.

Question 6.
A bag contains 12 blue balls and x red balls. If one ball is drawn at random (i) what is the probability that it will be a red ball? (ii) If 8 more red balls are put in the bag, and if the probability of drawing a red ball will be twice that of the probability in (i), then find x.
Answer:
Sample space = 12 + x
n(S) = x + 12
(i) Let A be the event of getting a red ball
n(A) = x
P(A) = \(\frac{n(\mathrm{A})}{n(\mathrm{S})}\) = \(\left(\frac{x}{x+12}\right)\)
(ii) 8 more red balls are added
Sample space = x + 12 + 8 = x + 20
Number of red balls = x + 8
Probability of drawing red ball = \(\frac{x+8}{x+20}\)
By the given condition
\(\frac{x+8}{x+20}=2\left(\frac{x}{x+12}\right)\)
(x + 8)(x + 12) = 2x(x + 20)
x² + 20x + 96 = 2x² + 40x
x² + 20x – 96 = 0
(x + 24)(x – 4) = 0
x = -24 (or) x = 4
The value of x = 4 (Number of balls will not be negative)
The probability of getting red balls = \(\left(\frac{x}{x+12}\right)=\frac{4}{16}=\frac{1}{4}\)

(ii) black or red
(iii) not white
(iv) neither white nor black
Answer:
Sample space (S) = 5 + 6 + 7 + 8
n(S) = 26
(i) Let A be the event of getting a white ball
n(A) = 6
\(P(A)=\frac{n(A)}{n(S)}\)
\(P(A)=\frac{6}{26}=\frac{3}{13}\)
(ii) Let A be the event of getting a black ball

Sample space (S) = 20 + x
n(S) = 20 + x
Let A be the event of getting to be defective
n(A) = x
\(P(A)=\frac{n(A)}{n(S)}\)
⇒ \(\frac{3}{8}=\frac{x}{20+x}\)
⇒ 8x = 3(20 + x) = (60 + 3x)

Question 12.
The king and queen of diamonds, queen and jack of hearts, jack and king of spades are removed from a deck of 52 playing cards and then well shuffled. Now one card is drawn at random from the remaining cards. Determine the probability that the card is
(i) a clavor
(ii) a queen of red card
(iii) a king of black card
Answer:
King diamond + Queen diamonds = 1 + 1 = 2 …….(1)
Queen hearts + Jack of hearts = 1 + 1 = 2 …….(2)
Jack spade + King of spades =1 + 1 = 2 …….(3)
Remaining number of cards = 52 – (6)
n(S) = 46
(i) Let A be the event of getting a clavor
n (A) = 13
\(P(A)=\frac{n(A)}{n(S)}=\frac{13}{46}\)
(ii) Let B be the event of getting a queen of red card
n(B) = 2
But the above two cards are removed from (1) and (2)
n(B) = 0
\(P(B)=\frac{n(B)}{n(S)}=\frac{0}{46}=0\)
(iii) Let B be the event of getting a king of black card
n(B) = (2 – 1) [from (3) one black card is removed]
n (B) = 1
\(P(B)=\frac{n(B)}{n(S)}=\frac{1}{46}\)

Question 13.
Some boys are playing a game, in which the stone thrown by them landing in a circular region given in the figure is considered as win and landing other than the circular region is considered as a loss. What is the probability to win the game?
Answer:

Area of a rectangle = l × b sq. feet = 3 × 4 sq. feet = 12 sq. feet
sample space (S) = 12
n(S) = 12
Let A be the event of getting the stone landing in a circular region
n(A) = Area of a circle
= πr²
= π × 1 × 1 (radius of a circle = 1 feet)
= π

Probability to win the game = \(\frac{11}{42}\) (or) \(\frac{157}{600}\)

Question 14.
Two customers Priya and Amuthan are visiting a particular shop in the same week (Monday to Saturday). Each is equally likely to visit the shop on any one day as on another day. What is the probability that both will visit the shop on
(i) the same day
(ii) different days
(iii) consecutive days?
Answer:
Sample space (S) = 6 × 6 = 36
n(S) = 36
[priya and Amuthan are visiting a particular shop in any one of 6 days is 6 × 6 = 36]
(i) Let A be the event of getting both are shopping on the same day
A = {(Mon, Mon) (Tue, Tue) (Wed, Wed) (Thu, Thu) (Fri, Fri) (Sat, Sat)}
n(A) = 6
\(P(A)=\frac{n(A)}{n(S)}\)
\(=\frac{6}{36}=\frac{1}{6}\)
(ii) Let B be the event of shopping in different days.
n(B) = 36 – 6 = 30
\(P(B)=\frac{n(B)}{n(S)}\)
\(=\frac{30}{36}=\frac{5}{6}\)
(iii) Let C be the event of shopping consecutive days
C = {(Mon, Tue) (Tue, Wed) (Wed, Thu) (Thu, Fri) (Fri, Sat)}
n(C) = 5
P(C) = \(\frac{n(\mathrm{C})}{n(\mathrm{S})}\) = \(\frac{5}{36}\)

Question 15.
In a game, the entry fee is ₹ 150. The game consists of tossing a coin 3 times. Dhana bought a ticket for entry. If one or two heads show, she gets her entry fee back. If she throws 3 heads, she receives double the entry fees. Otherwise, she will lose. Find the probability that she
(i) gets double entry fee
(ii) just gets her entry fee
(iii) loses the entry fee.
Answer:
Sample space (S) = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
n(S) = 8
(i) Let A be the event of getting double entry fee (only getting 3 heads)
n(A) = 1
\(P(A)=\frac{n(A)}{n(S)}=\frac{1}{8}\)
(ii) Let B be the event of getting her entry fee (one or two heads to show)
n(B) = Probability of one head + Probability of 2 head
= \(\frac{3}{8}+\frac{3}{8}=\frac{6}{8}=\frac{3}{4}\)
(iii) To loss the entry means not getting the head (only tail)
n(C) = 1
\(P(C)=\frac{n(C)}{n(S)}=\frac{1}{8}\)
