If the salary of A is 25% more than that of B, how much percentage is the salary of B lower than that of A? || ADRE 1.0 SLRC 2022 PAPER-III SOLVED QUESTIONS

If the salary of A is 25% more than that of B, how much percentage is the salary of B lower than that of A?

(A) 20%

(B) 25%

(C) 12 1/2%

(D) 16 2/3%

Solution:

Given, 

Salary of A is 25% more than that of B. 

Let's denote the salary of B as B.

So, the salary of A is:

A= 1.25B

To find how much percentage B's salary is lower than A's salary, we need to calculate the difference and express it as a percentage of A's salary. 

The difference between A and B is:

A-B= 1.25B-B 

⇒A-B= 0.25B

Now, the percentage difference is:

Percentage(%)= (A-B)/A*100

⇒ 0.25B/1.25B*100

⇒ 0.25/1.25*100

⇒ 20%

Therefore, the salary of B is 20% lower than that of A. 

So, the answer is: (A) 20%
