20%

Explanation:

Correct option 4: 20%

Given:
45% of (x - y) = 30% of (x + y)
Calculation:
45% of (x - y) = 30% of (x + y)
⇒(45/100) (x - y) = (30/100) (x + y)
Divide the above equation by 15 and 100 will be cut from both sides,
3(x-y)=2(x + y)
=3x-3y = 2x + 2y
=3x-2x= 2y + 3y
⇒x=5y
⇒ x/y = 5/1
⇒Percentage of x is y = (1/5) x 100
⇒20%
. The percentage of x is y is 20%.
