Mahesh purchased a radio at (9 / 10) of its selling price and sold it at 8% more than its original selling price. His gain percent is :
-
- 20 %
- 18%
- 10 %
- 8 %
Correct Option: A
Let the original selling price of radio = 10 U = $ 100
∴ C.P. of radio = 9 U = $ 90
When Mahesh sold it at 8% more than its original selling price , then
∴ New selling price = $ 108
Gain = New selling price - C.P. of radio = 108 - 90 = $ 18
| ∴ Gain percent = | × 100 | C.P. of radio |
| Gain percent = | × 100 = 20% | 90 |
