After allowing a discount of 11.11%, a trader still makes a gain of 14.28%. At how many percentage above the cost price does he mark on his goods?

1. 16%
2. 22.22%
3. 28.56%
4. 35%

Answer

Let Cost Price = x

Let Selling Price = y

x + (14.28x/100) = y - (11.11y/100)

y = 1.2856x

y = 128.56x/100

y = x + 28.56x/100

A trader marks his goods 28.56% above the cost price.

The correct option is C.
