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?

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?

A. 1 year B. 2 years C. 25 years D. Data inadequate E. None of these 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.
