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 :)
