Question

If A's salary is 30% more than B's salary, then by what percentage is B's salary less than that of A ? (correct to one decimal place)
1. 17.5%
2. 19.7%
3. 23.1%
4. 25%

Answer 1

Correct Answer - Option 3 : 23.1%

Given:

Salary of A is 30% more than salary of B.

Calculations:

Let the salary of B be 100x.

Salary of A  = 100x + 100x × 30%

⇒ 130x

Percentage Difference = {(130x - 100x)/130x} × 100

⇒ (30x/130x) × 100

⇒ 23.07% ≈ 23.1%

∴ B's salary is 23.1% less than that of A
