The printed price of an article is 40% higher than its cost price. Then the rate of discount such that he gains 12% profit is
-
- 21%
- 15%
- 20%
- 18%
Correct Option: D
Suppose C.P of article = Rs. 100
∴ Marked price = Rs. 140
At 12% gain, S.P. = Rs. 112
∴ Discount = Marked price - S.P. of article
∴ Discount = 140 – 112 = Rs. 28
If the rate of discount be y%, then
140 × y% = 28
| ⇒ | = 28 | 100 |
| ⇒ y = | = 20% | 140 |
