A number is first increased by 20% and then reduced by 20%. What would be the percentage change in the number?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Decrease by 4%.
Given:
A number is first increased by 20% and then reduced by 20%.
The successive percentage change in number = 20 - 20 - (20 × 20)/100
= - 400/100 = - 4%
Hence, the number is decreased by 4%.
