# What Profit does Really Make?

A shopkeeper marks his goods 30% above the cost price but allows a 10% discount for cash payment. What profit does really make?

- 13%
- 17%
- 20%
- 21%

**Answer: (2) 17 %**

**Explanation:-**

Let the cost price of the goods = Rs.100

A shop keeper marks his goods 30 % above the cost price.

Then, the cost price = 100 + 100 x 30/100

= 100 + 30

= Rs.130

He allows 10 % discount.

Then, the selling price = 130 – 130 x 10/100

= 130 – 13

= 117

The real profit = 117 – 100

= 17 %

Hence, the answer is (2) 17 %.
