The cost price of 15 articles is same as the selling price of 10 articles. The profit per cent is :
-
- 30%
- 40%
- 50%
- 45%
Correct Option: C
Suppose the C.P. of each article is $ 1
Then C.P. of 10 articles = $ 10
S.P. of 10 articles = $ 15
∴ Profit = 15 - 10 = $ 5
| % profit = | = 50% | 10 |
Second method to solve this question :
Here, p = 15, q = 10
| Profit% = | × 100 | q |
| Profit% = |  | 15 - 10 |  | × 240 = 50% | |
| 10 |
