The selling price of 12 articles is equal to the cost price of 15 articles. The gain percent is
-
-
6 2 % 3 - 20%
- 25%
- 80%
-
Correct Option: C
Let the CP of 1 articles = $ 1
∴ CP of 12 articles = $ 12
SP of 12 articles = $ 15
Gain = SP of 12 articles - CP of 12 articles = 15 - 12 = $ 3
| ∴ Gain percent = | × 100 | CP of 12 articles |
| Gain percent = | × 100 = 25% | 12 |
We can find gain % with the help of given formula :
Here, p = 15, q = 12
| Gain % = |  |  | × 100 | ||
| q |
| Gain % = | | | × 100 | ||
| 12 |
| Gain % = | × 100 = 25% | 12 |
