    Question

    A’s age is the sixth part of his father’s

    age. After 8 years, the age of A’s father will be twice the age of B. If B’s 6th birthday is celebrated 2 years ago, then what is the current age of A?
    A 7 years Correct Answer Incorrect Answer
    B 5 years Correct Answer Incorrect Answer
    C 6 years Correct Answer Incorrect Answer
    D 4 years Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let A’s age be x years and father’s age be 6x years. Present age of B = 6 + 2 = 8 years After 8 years, => 6x + 8 = 2(8 + 8) => 6x = 32 – 8 => x = 24/6 = 4 years
