Statement of the given problem,

The cost price of 15 articles is equal to the selling price of 12 articles. What is the gain percentage?

Let C & S denote the cost-price & the sell-price respectively of an article.

Hence from above data we get as follows,

12*S = 15*C

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

or S = (1 + 25/100)*C ….. (1)

Therefore from (1) it is evident that

the gain percentage = 25% [Ans]
