Question

Juhi sells a washing machine for ₹ 13,500. She loses 20% in the bargain. What was the price at which she bought it?

Sum
Advertisements

Solution

Selling price = ₹ 13500

Loss% = 20%

Let the cost price be x.

∴ Loss = 20% of x

Cost price − Loss = Selling price

`x - 20/100 xx x = 13500`

`x - 1/5 x = 13500`

`4/5 x = 13500`

`x = 13500 xx5/4`

x = 16875

Therefore, she bought it for ₹ 16875.
