    Question

    The ages of A, B and C together are 60 years. B is thrice as old as A and C is 5 years older than A. What is the difference between ages of B and C?

    A 18 years Correct Answer Incorrect Answer
    B 15 years Correct Answer Incorrect Answer
    C 13 years Correct Answer Incorrect Answer
    D 17 years Correct Answer Incorrect Answer
    E 11 years Correct Answer Incorrect Answer

    Solution

    Let A’s age be x years. B’s age = 3x and C’s age = (5 + x) According to question, => x + 3x + (5 + x) = 60 => 5x = 55 => x = 11 B’s age = 3x = 33 years C’s age = 5 + x = 16 years Difference between the ages of B and C = 33 – 16 = 17 years
