Correct Option: B
Let C.P. of 1 kg. of rice be Rs. 100.
According to the question,
∵ S.P. of 700 gm. of rice = Rs. 110
| ∴ S.P. of 1000 gm. of rice = | × 1000 | 700 |
| S.P. of 1000 gm. of rice = | = Rs. 157 | 7 | 7 |
| ∴ Profit = SP - CP = 157 | - 100 | 7 |
| Profit = 57 | 7 |
| ∴ Profit percent = 57 | % | 7 |
