    A 30.5 years Correct Answer Incorrect Answer
    B 20.5 years Correct Answer Incorrect Answer
    C 21 years Correct Answer Incorrect Answer
    D 19.5 years Correct Answer Incorrect Answer
    E 30.5 years Correct Answer Incorrect Answer

    Solution

    Age of Dimple, 4 years hence from now = 20 years So, the present age of Dimple = 20 - 4 = 16 years So, the present age of Rishi = 16 X (25/16) = 25 years The present age of Selina = 25 - 5 = 20 years Or, the present age of Anmol = 16 + 5 = 21 years Therefore, required average age = (20 + 21) /2 = 20.5 years
