If a shopkeeper marks the price of goods 50% more than their cost price and allows a discount of 40%, what is his gain or loss percent ?
-
- Gain of 10%
- Loss of 10%
- Gain of 20%
- Loss of 20%
Correct Option: B
Let C.P. of article = ₹ 100
Marked price = ₹ 150
| S.P. = | = ₹ 90 | |
| 100 |
Loss = 100 – 90 = ₹ 10 i.e. 10%
2nd method to solve this question.
Here, r = 50%, r1 = 40%
| His loss % = | − r1 | |
| 100 |
| Loss % = | − 40 | |
| 100 |
| Loss % = | − 40 | |
| 100 |
Loss % = –10% (–ve sign shows loss)
Required Loss % = 10% loss
