The selling price of a book is ₹855. If the loss incurred through the sale is 10%, then what is the nominal amount of loss incurred?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. ₹95

Let the cost price of the book be ₹x-

So,

Loss% = (CP−SPCP)×100\left ( \frac{CP-SP}{CP}\right )\times 100

10% = ​​​​(x−855x)×100​​​​\left ( \frac{x-855}{x}\right )\times 100

10x = 100x - 85500

85500 = 100x - 10x

85500 = 90x

So,

x = 85500 ÷ 90 

x = 950

So,

Nominal loss incurred = 950 - 855 = ₹95
