Question 102

How much percent more than the cost price should a shopkeeper mark his goods so that after allowing a discount of 25% on the marked price, he gains 20% ?

Solution

Let C.P. of article = Rs. 100 and the marked price of the article = Rs. $$x$$

Amount after profit = $$100 + \frac{20}{100} * 100 = 120$$

=> $$x \times \frac{75}{100} = 120$$

=> $$x = \frac{120 * 100}{75} = 160$$

i.e. 60% above cost price.
