Answer 1

25%

process:

Statement of the given problem,

By selling 75 apples, a seller gains the selling price of 15. What is the profit or loss percent?

Let C & S denote the cos-price & the sell-price of an apple.

Hence from above data we get as follows,

75*S - 75*C = 15*S

or 60*S = 75*C or S = (5/4)*C = (1 + 1/4)*C

or S = (1 + 25/100)*C …. (1)

Therefore from (1) it is evident that

profit percentage = 25% [Ans]
