Question

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 his goods?

• A. 28.56%
• B. 35%
• C. 22.22%
• D. None of these

Hint:

When both discount and profit/loss are given, work with CP as base for easier calculation.

Answer 1

The Correct Option is B

Let CP = 100. Profit = 14.28% $\Rightarrow$ SP = 114.28. Discount = 11.11% on MP $\Rightarrow$ SP = MP $\times \frac{8}{9}$. So, $114.28 = \frac{8}{9} \times MP \Rightarrow MP = 114.28 \times \frac{9}{8} \approx 128.565$. Mark-up = $\frac{128.565 - 100}{100} \times 100 \approx 28.565%$.
