    Question

    A is 4 years older than B who is twice as old as C. The

    total sum of the ages of A, B and C is 34. How old is B?
    A 16 years Correct Answer Incorrect Answer
    B 24 years Correct Answer Incorrect Answer
    C 12 years Correct Answer Incorrect Answer
    D 20 years Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the present age of C be x years. Now, B’s age will be = 2x And A’s age will be = (4 + 2x) According to the question, => A + B + C = 34 => (4 + 2x) + 2x + x = 34 => 5x = 30 => x = 6 Therefore the age of B = 2×6 = 12 years
