Question

A number is increased by 20%. To get back the original number, the increased number is to be reduced by:
1. 21%
2. 16.67%
3. 25%
4. 20%

Answer 1

Correct Answer - Option 2 : 16.67%

Calculation:

Let this number be 100

Number increased by 20%

New number = 100 × (120/100) = 120

To get back the original number, new number should be reduced by = 120 – 100 = 20

Reduced % = (20/120) × 100 = 16.67%

∴ The new number should be reduced by 16.67% to get the original number
