1. Increasing the original price of an item by 20% and then decreasing the price by 20% is equivalent to which of the following?
- A. 4% decrease
- B. 4% decrease
- C. 4% decrease
- D. 4% decrease
Answer: Option A
Explanation:
let the number is 100
increase 20% = 100 + 20 = 120
decrease of 20% on 120 = (20/100)×120 = 24
nett amount 120–24 = 96
So decrease 100–96 = 4
decrease of 4 out of 100
percentage of decrease 4%
