Question

During a sale, a shopkeeper reduced the prices of all his goods by 25%.

Calculate the normal selling price of a pair of shoes which was sold for Rs 1350 in the sale.

Answer 1

let be the real price x :

x - x × ( 25/100 ) = 1350

x - x × ( 1/4 ) = 1350

x - x/4 = 1350

4x - x / 4 = 1350

3x / 4 = 1350

3x = 1350 × 4

3x = 5400

x = 5400 ÷ 3

x = Rs 1800
