A coconut merchant finds that the cost price of 2750 coconuts is the same as the selling price of 2500 coconuts. The loss or gain per cent is
-
- 5% loss
- 15% loss
- 20% gain
- 10% gain
Correct Option: D
Let CP of each coconut be $ 1.
∴ CP of 2500 coconuts = $ 2500
SP of 2500 coconuts = $ 2750
Gain = 2750 - 2500 = $ 250
| ∴ Gain percent = | × 100 | CP of 2500 coconuts |
| Gain percent = | × 100 | 2500 |
Second method to solve this question :
Here, p = 2750, q = 2500
| Gain % = |  | p - q |  | × 100 | |
| q |
| Gain % = | | 2750 - 2500 | | × 100 | |
| 2500 |
| Gain % = | × 100 = 10% | 2500 |
