Question

A person sells potatoes in 10% profit. If he would sell each kg of potato 3rs less, then he would have 20% loss. What is the selling price of each kg potato?​

Answer 1

Answer:

11 (Rs)

Step-by-step explanation:

According to given problem,

(i) A person sells potatoes in 10% profit. If he would sell each kg of potato Rs.3 less, then he would have 20% loss.

(ii) Let C & S denote cost-price & sell-price of each kg potato.

From (i) & (ii) we get following relations,

S = (1 + 10/100)*C = 1.1*C …. (1a)

S - 3 = (1 - 20/100)*C = 0.8*C …. (1b)

From (1b) & (1a) we get,

S - 3 = (0.8/1.1)*S

or S - (8/11)*S = 3 or (3/11)*S = 3 or S = 11 (Rs) [Ans]
