Question

A number A is increased by 20% to get another number B . By what percent should B be reduced to get back A?

• A. 16.67%
• B. 20%
• C. 25%
• D. 33.33%

Answer 1

The correct option is A 16.67%

Let the number A be 100
After increment, B = 20% of 100 + 100 = 120
Now, in order to reduce to 100, 20 needs to be subtracted from 120

So, the required percent = $\frac{20}{120}\times 100$% =16.67%

Hence, option A is the correct answer.
