Q is as much younger than R as he is older than T. If the sum of the ages of R and T is 50 years, what is definitely the difference between R and Q’s age? Choose the correct option
A) 1 year  B) 2 years  C) 25 years  D) Data inadequate  E) None of these
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.   Answer Data inadequate

Q is as much younger than R as he is older than T. If the sum of the ages of R and T is 50 years, what is definitely the difference between R and Q’s age?
