Question

A shopkeeper marks his goods at 40%above the cost price and offers a discount of 20%.What is his gain per cent

Answer 1

let the cost price be ' x '

according to question ,

market price = x + 40% of x = x + 0.4 x

market price = 1.4 x

discount offered = 20 % of 1.4 x

= 0.2 × 1.4 x = 0.28 x

selling price = market price - discount offered

selling price = 1.4 x - 0.28 x = 1.12 x

gain=selling price - cost price =1.12x - x

= x ( 1.12 - 1 ) = 0.12 x

gain % = gain / cost price × 100

=0.12 x / x × 100 = 12 %

therefore, gain = 12%
