If quantity $A$ is $25\%$ greater than quantity $B$, by what percentage is quantity $B$ less than quantity $A$?

Options:

  • (A) 20%
  • (B) 25%
  • (C) 16.67%
  • (D) 33.33%

Answer Key:

A

Step-by-Step Solution & Explanation

Let $B = 100$. Then $A = 100 \times 1.25 = 125$. The difference between $A$ and $B$ is $125 - 100 = 25$. The percentage by which $B$ is less than $A$ is: $\text{Percentage} = \frac{25}{125} \times 100\% = \frac{1}{5} \times 100\% = 20\%$
