A number is increased by 20% and then decreased by 20%. What is the net change in the number?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 4% decrease.
Let the number be 100 (easy assumption).
- Increase by 20% → 100 + 20 = 120
- Decrease by 20% → 120 − 24 = 96
Net Change:
- Final value = 96 (from 100)
- Change = 100 − 96 = 4
Net change = 4% decrease
