Answer 1

Answer:

Loss = 33 1/3 %

Step-by-step explanation:

Let the cost price of 1 book be x

Then the cost price of 10 books is ₹ 10x

Selling price of 15 books = Cost price of 10 books

Selling price of 15 books = 10x

Selling price of 1 book = ₹ 10x/15

Loss = C.P. - S.P. = x - 10x/15 = 15x -10x/15 = 5x/15 = x/3

Loss% = Loss/C.P. × 100 = x/3x × 100 = 100/3% = 33 1/3 %
