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

1. $28.56$%
2. $35$%
3. $22.22$%
4. None of these

11.11% = 1/9

14.28% = 1/7

Let us suppose that markup price is 9x. After discount, SP becomes 8x

It is given that after making the discount, the trader makes gain of 14.28%. So, the CP becomes 7x

Thus, he mark his goods 2/7 i.e. 28.56% above CP
