Question 3.

Fill up the appropriate boxes in the following table.

Solution:

(i) CP = Rs 100

SP = Rs 120

CP < SP

Profit = SP – CP

= Rs 120 – Rs 100

= Rs 20

(ii) CP = Rs 110

SP = Rs 120

CP < SP

Profit = SP – CP

= Rs 120 – Rs 110

= Rs 10

(iii) CP = Rs 120

Profit = Rs 20

Profit = SP – CP

Rs 20 = SP – Rs 120

Rs 20 + Rs 120 = SP

SP = Rs 140

(iv) CP = Rs 100

SP = Rs 90

CP > SP

Loss = CP – SP

= Rs 100 – Rs 90

= Rs 10

(v) CP = Rs 120

Profit = Rs 25

Profit = SP – CP

Rs 25 = SP – Rs 120

Rs 25 + Rs 120 = SP

Rs 145 = SP

SP = Rs 145

Question 4.

Fill up the appropriate boxes in the following table.

Solution:

(i) CP = Rs 110

MP = Rs 130

Profit = SP – CP

= Rs 130 – Rs.110

= Rs 20

If there is no discount MP = SP

SP = Rs 130

(ii) CP = Rs 110 Profit

MP = 130

Discount = Rs 10

= SP – CP

= Rs 120 – Rs 110

= Rs 10

SP = MP – Discount

= Rs 130 – Rs 10

= Rs 120

(iii) CP = Rs 110

MP = Rs 130

Discount = Rs 30

Loss = CP – SP

= Rs 110 – Rs 100

= Rs 10

SP = Mp – Discount

= Rs 130 – Rs 30

= Rs 100

(iv) CP = Rs 110

MP = Rs 120

Loss = CP – SP

SP = CP – Loss

= Rs 110 – Rs 10

= Rs 100

Discount = MP – SP

= Rs 120 – Rs 100

= Rs 20

(v) MP = Rs 120

Discount = Rs 10

Profit = Rs 20

Loss = Rs 0

SP = MP – Discount

= Rs 120 – Rs 10

= Rs 110

Profit = Rs 20

= SP – CP

Rs 20 = Rs 110 – CP

CP = SP – Profit

= Rs 110 – Rs 20

= Rs 90

Question 13.

Valavan bought 24 eggs for ₹ 96. Four of them were broken and also he had a loss of ₹ 36 on selling them. What is the selling price of one egg?

Solution:

Cost of 24 eggs = Rs 96

Since 4 of the eggs were broken, the number of remaining eggs = 24 – 4 = 20

Since the loss is Rs 36

The selling price of 20 eggs

SP = CP – Loss

= Rs 96 – Rs 36

= Rs 60

∴ Cost of 1 egg = Rs 60 / 20 = Rs. 3
