Question

If the cost price of 13 books is equal to the selling price of 12 books, find the profit percent.

Please solve this math​

Answer 1

Step-by-step explanation:

Let cost price of a book = P , cost price of 13 book = 13 P

As S.P > C.P , So, there is profit.

Profit = 13P - 12P= 1P

Profit % = Profit x 100/C.P

Profit % = 1P x 100/10P = 100/10 = 10%
