    Answer : Option A

    Explanation :

    Let the age of son is X and age of father 7X

    Age of son after 10 years = X+10

    Age of father after 10 years = 7X + 10

    As per question, after 10 years;

    3(X+10) = 7X + 10

    3X + 30 = 7X + 10

    4X = 20

    X = 5 years

    ∴Age of father now = 7 * 5 = 35 years
