उत्तर

This statement is False.

Explanation:

Given, S.P. = ₹ 50 and loss percent = 10%

We know that, Loss % = `"Loss"/"C.P." xx 100%`

⇒ Loss % = `("C.P." - "S.P.")/"C.P." xx 100`  ......[∵ Loss = C.P. – S.P.]

⇒ 10 = `(("C.P." - 50))/"C.P." xx 100`

⇒ 10C.P. = 100C.P. – 5000

⇒ 90C.P. = 5000

⇒ C.P. = `5000/90`

∴ C.P. = ₹ 55.55

Hence, the cost price of the book is ₹ 55.55
