Question

A seller selling 10 books for ₹ 15 earns a profit equal to the purchase price of the books. find the percentage profit and also calculate purchase price per book. [Ans - Profit = 100% and Cost price = 75]​

Answer 1

Answer:

cost price= 75 Rs   profit = 100%

Step-by-step explanation:

selling price = 150 rs

cost price = profit

thus, cost price + cost price = selling price

2 (cost price ) = 150

cost price = 150/ 2

thus, cost price = 75 Rs

therefore, profit = 75 Rs

therefore, profit % = 75/75 * 100

                              = 1 * 100

                              = 100 %
