Ques - The profit percentage of A and B is same on selling the articles at Rs. 1800 each but A calculates his profit on the selling price while B calculates it correctly on the cost price which is equal to 20%. What is the difference in their profits?

(a) Rs. 360

(b) Rs. 60

(c) Rs. 540

(d) Rs. 450

Solution -

SP of the article = 1800

Profit of A = 1800 × (20/100)

= Rs. 360

And,

Profit % = [(SP - CP) / CP] × 100

20 = [(1800 - CP) / CP] × 100

20/100 = [(1800 - CP) / CP]

CP = 5(1800 - CP)

CP = 9000 - 5CP

CP + 5CP = 9000

6CP = 9000

CP = 9000/6

CP = 1500

Thus,

Profit of B = SP - CP

= 1800 - 1500

= 300

Therefore,

The difference in profits of A and B = Profit of A - Profit of B

= 360 - 300

= 60

Hence,

The correct answer is option (b) Rs. 60.
