Question : If A's salary is 60% more than B's salary, then by what percentage is B's salary less than that of A?
Option 1: 45%
Option 2: 37.5%
Option 3: 47.7%
Option 4: 33.3%
Correct Answer: 37.5%
Solution :
A = B + 60% of B
A = 160% of B
A : B = 160 : 100 = 8 : 5
The required percentage = $\frac{\text{A's salary – B's salary}}{ \text{A's salary}}\times 100$
= $\frac{8-5}{8} \times 100 $
= 37.5%
Hence, the correct answer is 37.5%.
