Question

A trader marks his goods 20% above cost price but allows a discount of 5% his gain % is=?

Answer 1

Let cost price = x

Selling Price = x + 20% of x

Selling Price = x + (20/100)*x

Selling Price = x + (1/5)*x = 6x/5

5% of discount on Selling Price = 5% of 6x/5 = (5/100)*(6x/5) = 3x/50

Selling price after 5% discount = (6x/5) - (3x/50) = 57x/50

Gain Amount = (57x/50) - x = 7x/50

Gain % = (7/50)*100 = 14% ——> Answer
