    Answer: (3) 36 years

    Explanation:-
    Let the age of Rajan and Ashok be X & Y years

    Rajan’s age is 3 times than that of Ashok.
    Then,  X = 3 Y
    X – 3 Y = 0   ………………………….. (1)

    In 12 years, Rajan’s age will be double the age of Ashok.
    Then,  X + 12 = 2 (Y + 12)
    X + 12 = 2 Y + 24
    X – 2 Y = 24 – 12
    X – 2 Y = 12 ……………………..(2)

    Equation (2) Subtract from equation (1),
    X  – 3 Y – X + 2 Y = – 12
    – Y = – 12
    Y = 12

    Then, the age of Rajan = X = 3 x 12
    = 36 years.

    Hence, the correct answer is option (3) 36 years.
