Question : A is 5 times B. B is how much percentage less than A?
Option 1: 80%
Option 2: 60%
Option 3: 52.5%
Option 4: 83.33%
Correct Answer: 80%
Solution :
Given: A is 5 times B.
A = 5B
So, if B = 1, then A = 5.
Required percentage = $\frac{A–B}{A}\times 100=\frac{5–1}{5}\times 100=\frac{4}{5}\times 100=80$%
Hence, the correct answer is 80%.
