Question
The price of an article is increased by 20% and then decreased by 20%. Find the net percentage increase or decrease in the price.
Solution
ATQ, Assume original price = 100. After 20% increase: Price = 120 After 20% decrease: Price = 120 − 20% of 120 = 120 − 24 = 96 Net change = 96 − 100 = −4 So price decreases by 4%.
