The cost price of 91 books is equal to the selling price of 65 books. ...
Given:
The cost price of 91 books is equal to the selling price of 65 books.
Concept used:
Profit = SP - CP
Profit% = Profit/CP × 100 
Calculation:
Let the cost price of each book be Rs. 1
CP of 65 books = Rs. 65
SP of 65 books = CP of 91 books = Rs. 91
