If the selling price of 10 articles is equal to the cost price of 11 articles, then the gain percent is
-
- 10%
- 11%
- 15%
- 25%
Correct Option: A
Let the C.P. of each article be $ 1.
∴ C.P. of 10 articles = $ 10
and S.P. of 10 articles = $ 11
Profit = S.P. of 10 articles - C.P. of 10 articles = 11 - 10 = $ 1
| ∴ Profit percent = | × 100 | C.P. of 10 articles |
| Profit percent = | × 100 = 10% | 10 |
Second method to solve this question :
Here, p = 11, q = 10
| Profit % = |  | p - q |  | × 100 | |
| q |
| Profit % = | | 11 - 10 | | × 100 | |
| 10 |
| = | = 10% | 10 |
