Let the son's age be x ∴his father's age=3x after 12 yrs son's age=x+12 ∴after 12 yrs his father's age = 3x+12 From the question : 3x+12=2(x+12) (∵ father's age will be twice that of his son) ∴3x+12=2x+24 3x - 2x=24 - 12 ∴x=12 ∴the present age of son = 12 Hope it helps and pls mark this as best answer :)
