If the cost price of 12 oranges is equal to selling price of 10 oranges, then the percentage of profit is
-
-
16 2 % 3 - 20%
- 18%
- 25%
-
Correct Option: B
Let C.P. of each orange be $ 1
Then, C.P. of 10 oranges = $ 10
S.P. of 10 oranges = $ 12
Gain = 12 - 10 = $ 2
| ∴ Gain % = | Gain | × 100 |
| C.P. of 10 oranges |
| Gain % = |  | 2 | × 100 |  | % = 20% |
| 10 |
Second method to solve this question :
Here, p = 12, q = 10
| Profit % = | | p - q | | × 100 | |
| q |
| Profit % = | | 12 - 10 | | × 100 = 20% | |
| 10 |
