Question

The cost price of 25 books is the same as the selling price of 35 books. Find the lost percentage. ​

Answer 1

Step-by-step explanation:

Let the cost price of one book be Re 1,

then the cost price of 25 books is Rs 25

The selling price of 35 books = cost price of 25 books = Rs 25

Now, let us find the cost price for 35 books We have assumed the cost of 1 book = Re 1. Therefore, cost price of 35 books = Rs 35

Therefore, the profit/loss made on 35 books = S.P of 35 books - C.P of 35 books = Rs 35 – Rs 25 = Rs 10 Hence, Loss percent = (10/35) ´ 100 = 28.57%
