Question 108

20% raise of price followed by a discount of 25% of the raised portion will

Solution

Let original price = $$100x$$

Raise of 20% => $$\frac{20}{100} * 100x = 20x$$

=> Price becomes = $$100x+20x = 120x$$

Now, 25% discount on 'raised' price = $$\frac{25}{100} * 20x = 5x$$

=> New price = $$120x-5x = 115x$$

which is 15 % more than the original price.
