Question

If A's salary is $25\%$ higher than B's salary, then how many percent is B's salary lower than A's?

Answer 1

Let B's salary = 100

Hence, A's salary = 125

Now B's salary is $(100\ast \frac{100}{125})\%$ of A's salary.

Which gives B's salary is $80\%$ of A's salary.

Hence B's salary is $100-80=20\%$ lower then A's salary.
