A dealer marks his goods 20% above their cost prices. Then, he allows such a discount on the marked price so that he makes a profit of 8%. The rate of discount is :
-
- 12%
- 10%
- 6%
- 4%
Correct Option: B
Let the C.P. of article be Rs. 100.
∴ Its marked price = Rs. 120
Let the rate of discount be y%
At 8% profit , S.P. of article = 100 + 8 = Rs. 108
According to the question,
y% of 120 = Marked price - S.P. of article
⇒ y% of 120 = 120 – 108
| ⇒ | = 12 | |
| 100 |
| ⇒ y = | = 10% | |
| 120 |
