Question

the cp of 10 book is same as sp of 8 book find the profit percentage​

Answer 1

Answer:

Statement of the given problem,

If the cost price of 12 books is equal to the selling price of 8 books, what is the gain percent?

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

Hence from above data we get as follows,

8*S = 12*C

or S = (3/2)*C = (1 + 1/2)*C = (1 + 50/100)*C

Therefore the gain percentage = 50% [Ans]
