    Explanation:

    Let the present age of the man and his son be x and y respectively So,

    x – 5= 4(y-5) +3 x – 4y= -12 (i)

    Again X+3 = 3(y+3) -6 x – 3y= 0 (ii)

    By solving, we get X= 36, y=12

    Sum of their ages = 48

    Hence after 16 years the sum of their ages will be 80 years.
