If a person marks a product 25% above the cost price but allows 10% discount, then the percentage of profit is
-
- 35 %
- 15 %
- 17.5 %
- 12.5 %
Correct Option: D
As we know the formula for profit %
| Profit percent = |  | q + r + |  | % | |
| 100 |
| = | | 25 − 10 − | | % | |
| 100 |
= (15 – 2.5)% = 12.5 %
2nd method to solve this question.
Here = r = 25%, r1 = 10%
| ⇒ Gain % = | − r1 | |
| 100 |
| Gain % = | − 10 | |
| 100 |
| Gain % = | − 10 | |
| 100 |
Required Gain % = 22.5 – 10 = 12.5%
