-
- 25%
-
133 1 % 3
-
33 1 % 3
- 30%
Correct Option: C
Let the Cost Price ( CP ) = $ 100
Then, Selling Price ( SP ) = $ 120
Let the marked price = $ y.
Then, 90% of y = $ 120
| ⇒ | = $ 120 | 100 |
| ⇒ y = | = | 90 | 3 |
| ⇒ x = 133 | % | 3 |
| Hence, the marked price is 33 | above the cost price. | 3 |
