Question 109

A shopkeeper marks his goods 20% above his cost price and gives 15% discount on the marked price. His gain percent is

Solution

Let C.P. = $$100x$$

20% above marked price = $$\frac{20}{100} * 100x = 20x$$

=> M.P. = $$100x+20x = 120x$$

Discounted amount = $$\frac{15}{100} * 120x = 18x$$

=> S.P. = $$120x-18x = 102x$$

Profit % = $$\frac{102x - 100x}{100x}$$ * 100 = 2%
