A tradesman allows a discount of 15% on the marked price. How much above the cost price must he mark his goods as to gain 19%?
-
- 34%
- 40%
- 25%
- 30%
Correct Option: B
Here, r = 15% and R = 19%
∴ Requirement percentage = [(r + R) / (100 - r)] x 100%
= [(15 + 19) / (100 - 15)] x 100% = [(34 x 100) / 85 ] % = 40%
