# A Dealer Marks his Goods 20% Above Cost Price :

A dealer marks his goods 20% above cost price and allows a discount of 10% to his customers. His gain percentage is

- 6%
- 7%
- 8%
- 9%

**Answer: (3) 8%**

**Explanation:-
**Let the cost price of goods = Rs. 100

A dealer marks his goods 20% above cost price.

Then, the price of goods = 100 +100 x 20/100

= 100 + 20

= Rs. 120

He gave 10% discount,

Then, selling price = 120 – 120 x 10/100

= 120 – 12

= Rs. 108

Gain% = 108 – 100

= 8%

Then, he gain percent is 8.

Hence, the answer is (3) 8%.
