Question

Salary of X is 20% more than that of Y. By what percentage is the salary of Y lesser than X?

Answer 1

Step-by-step explanation:

Let X salary = 100.

Y should be = (X + 20% more)

So Y salary = 100+ (20% of 100) = 120.

while finding percentage we should be clear with BASE

here we need to find Y is what percentage of X

so formula be (Y-X) / Y

that gives us (120-100) / 120

= (20)/120

= 1/6

or 16.67 percent
