Question
A shopkeeper sold an article at marked price and got a
profit of 60%. If he had given a discount of 10%, then find his new profit percent.Solution
ATQ, Let the cost price of the product be Rs. 100 Then, marked price = selling price = 100 × 1.60 = Rs. 160 If he allows a discount of 10%, then new selling price = 0.90 × 160 = Rs. 144 New Profit = (144 – 100) = Rs. 44 So, required profit percentage = 44%
