Question

A book was sold for Rs.575 therby gaining 15%
find c.p. of the book.​

Answer 1

Answer:

Given,

Selling price of book = Rs. 575

Let cost price of book be Rs.a.

⇒ 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
