Question

If x is 20% less than y, then find value of y-x/y and x/x-y

Answer 1

Dear Student,

◆ Answer -

(y-x)/y = 1/5

x/(x-y) = -4

● Explanation -

Given that x is 20% less than y.

x = y × (100-20)/100

x = y × 80/100

x = 4y/5

Value of (y-x)/y is -

(y-x)/y = (y - 4y/5) / y

(y-x)/y = (y/5) / y

(y-x)/y = 1/5

Value of x/(x-y) is -

x/(x-y) = (4y/5) / (4y/5 - y)

x/(x-y) = (4y/5) / (-y/5)

x/(x-y) = -4

Hope this helps you..
