    Question

    The ages of A, B and C together are 54 years. B is twice as old as A and C is 6 years older than A. What is the difference between ages of B and C?

    A 8 years Correct Answer Incorrect Answer
    B 5 years Correct Answer Incorrect Answer
    C 3 years Correct Answer Incorrect Answer
    D 6 years Correct Answer Incorrect Answer

    Solution

    Let A’s age be x years. B’s age = 2x and C’s age = (6 + x) According to question, => x + 2x + (6 + x) = 54 => 4x = 48 => x = 12 B’s age = 2x = 24 years C’s age = 6 + x = 18 years Difference between the ages of B and C = 24 – 18 = 6 years
