Question

A shopkeeper marks his goods at 30 percent

above the cost price and then gives a discount
of 10 percent. Find his gain percent.​

Answer 1

Explanation:

Let the cost price be = $ 100

Increased price = 100 * 30/100 = $30

Market price = 100 +30 = $130

Discount amount = 10% of 130 = 10/100 * 130 = $ 13

Price after discount = 130 - 13 = $ 117

Gain = 117 - 100 = 17

Gain = 17%
