Question

    A’s age is the fourth 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 7th birthday is celebrated 3 years ago, then what is the current age of A?
    A 7 years Correct Answer Incorrect Answer
    B 4 years Correct Answer Incorrect Answer
    C 6 years Correct Answer Incorrect Answer
    D 5 years Correct Answer Incorrect Answer
    E 8 years Correct Answer Incorrect Answer

    Solution

    Let A’s age be x years and father’s age be 4x years. Present age of B = 7 + 3 = 10 years After 8 years, => 4x + 8 = 2(10 + 8) => 4x = 36 – 8 => x = 28/4 = 7 years
