-
- 12.1% profit
- 12.1% loss
- 12.2% profit
- 11.1% loss
Correct Option: C
Let C.P. of each camera = Rs. y
For profit of 18% ,
| S.P. of first camera = Rs. | 100 |
On 10% less ,
| S.P. of second camera = | × | 100 | 100 |
| = Rs. | 1000 |
| Profit = | + | - 2y | 100 | 1000 |
| Profit = | 1000 |
| Profit = Rs. | 1000 |
| ∴ Gain percent = | × 100 = 12.2% | 1000 × 2y |
