Question

a shopkeeper marks his good 20% above cost price and allows a discount of 15% what per cent does he gain or lose?​

Answer 1

Explanation:

Let the cost price (CP) be Rs 100

Marked price = CP + 20% of Cost Price

Marked Price =(100+20)% of 100=100+10020×100=120

Discount of 15% on marked price is given

Hence, selling price = Marked Price - 15% of Marked Price

Selling Price = 120−10015×120 = 120−18= Rs 102

Profit =SP−CP=102−100=Rs 2

Now, Profit Percent =CPProfit×100=1002×100=2%
