    Answer : Option D

    Explanation :

    Given that:

    1. The difference of age b/w R and Q = The difference of age b/w Q and T.

    2. Sum of age of R and T is 50 i.e. (R + T) = 50.

    Question: R - Q = ?.

    Explanation:

    R - Q = Q - T

    (R + T) = 2Q

    Now given that, (R + T) = 50

    So, 50 = 2Q and therefore Q = 25.

    Question is (R - Q) = ?

    Here we know the value(age) of Q (25), but we don't know the age of R.

    Therefore, (R-Q) cannot be determined.
