Question

Answer 1

Given,

Selling price of book = Rs. 575

Let cost price of book be Rs.a.

Concept Used:

Profit = S.P - C.P

Loss = C.P - S.P

Calculation:

⇒ Profit = 575 - a

Given,

Selling price of book = Rs. 385

⇒ Loss = a - 385

Then,

⇒ 575 - a = a - 385

⇒ 2a = 960

⇒ a = 480

∴ cost price of a book is Rs. 480
