Question

What price should a shopkeeper mark on an article costing him Rs 153 to gain 20percent after allowing a discount of 15percent?

Answer 1

cost price of the article = 153

required gain percentage after 15% discount = 20%

gain = cost price * gain percentage = 153 * 20% = 30.6

total selling price before discount = 153 + 30.6 = 183.6

shopkeeper should mark on an article costing him Rs 153 to gain 20% after allowing a discount of 15%

let the final selling price be x

then final selling price - discount rate = selling price before discount

 x - 15%(x) = 183.6

x - 15x/100 = 183.6

x - 0.15x = 183.6

0.85x = 183.6

x = 183.6/0.85 = 216 = mark up price
