-
- 65%
- 60%
- 15%
- 75%
Correct Option: B
Let cost price of 1 article = $ 1
Then , Cost price of 25 articles = $ 25
Selling price of 25 articles = $ 40
Gain = Selling price of 25 articles - Cost price of 25 articles = 40 - 25 = $ 15
| Gain percent = | × 100 | Cost price of 25 articles |
| Gain percent = | × 100 = 60% | 25 |
We can find gain % with the help of given formula :
Here, p = 40, q = 25
| Gain % = |  |  | × 100 | ||
| q |
| Gain % = | | | × 100 | ||
| 25 |
| Gain % = | × 100 = 60% | 25 |
