Correct Option: B
Let the marked price of book be Rs. 100.
C.P. for the retailer = Rs. (100 – 30) = Rs. 70
On 10% discount , S.P. for the retailer = Rs. 90
Profit = S.P. - C.P. = 90 - 70 = Rs. 20
| ∴ Profit percent = |  |  | × 100 | |
| C.P. for the retailer |
| Profit percent = | = 28 | % | ||
| 70 | 7 |
