Question

find the percentage of profit-loss of 10 eggs is equal to sale price of 11 eggs.​

Answer 1

Step-by-step explanation:

According to given problem,

(i) The selling price of 10 eggs is equal to the cost of 11 eggs.

(ii) Let C & S denote respectively the cost-price & the sell-price of 1 egg.

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

10*S = 11*C

or S = (10/11)*C = (5/4)*C

or S = (1 + 1/4)*C

or S = (1 + 25/100)*C …… (1a)

Therefore

it is evident from (1a) that the required gain percentage = 25% [Ans]
