    Question

    The present age of a father is three times that of his

    son. After 10 years, the father’s age will be twice that of his son. What are their current ages?
    A Father: 30, Son: 10 Correct Answer Incorrect Answer
    B Father: 36, Son: 12 Correct Answer Incorrect Answer
    C Father: 60, Son: 20 Correct Answer Incorrect Answer
    D Father: 48, Son: 16 Correct Answer Incorrect Answer

    Solution

    Let son’s age = x, and father’s age = 3x. After 10 years, father’s age = 3x + 10, and son’s age = x + 10. (3x + 10) = 2(x + 10) Solving for x, x = 10. Father’s age = 3(10) = 30, Son’s age = 10. Correct Option: a) Father: 30, Son: 10
