    Question

    The ages of A and B are in the ratio 5:7. If the sum of

    their ages is 72 years, what will be A's age after 6 years?
    A 24 years Correct Answer Incorrect Answer
    B 30 years Correct Answer Incorrect Answer
    C 36 years Correct Answer Incorrect Answer
    D 42 years Correct Answer Incorrect Answer

    Solution

    Let A's age be 5x and B's age be 7x. 5x + 7x = 72 → 12x = 72 → x = 6. A's current age = 5x = 30 years. A's age after 6 years = 30 + 6 = 36 years.
