The cost price of 400 lemons is equal to the selling price of 320 lemons. Then the profit percent is
-
- 15%
- 20%
- 25%
- 40%
Correct Option: C
Let the CP of 1 lemon = $ 1
∴ CP of 320 lemons = $ 320
SP of 320 lemons = $ 400
If SP > CP , then
Profit = SP of 320 lemons - CP of 320 lemons = 400 - 320 = $ 80
| Profit percent = | × 100 | CP of 320 lemons |
| Profit percent = | × 100 = 25% | 320 |
Second method to solve this question :
Here, p = 400, q = 320
| Gain % = |  |  | × 100 | ||
| q |
| Gain % = | | | × 100 | ||
| 320 |
| Gain % = | × 100 = 25% | 320 |
