    Answer:

    present age of father and son =7:1 (in ratio )

    let the given ratio be, 7x and 1x

    After 10 years their ages will be,

    father’s age:7x+10 years

    son’s age :1x+10 years

    Now,

    After 10 years ages will be in 2:1 ratio

    = 2x, 1x

    7x+10 = 2x

    ——— —— (cross multiplication)

    1x+10 1x

    7x+10*1x = 1x+10*2x

    7x-2x =10-10

    5x = 0

    therefore X = 5

    Now,

    present age of father =7x =) 7*5 = 35 years

    present age of son = 1x =) 1*5 = 5 years.
