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

• Ans.D
  The difference between R & Q and Q & T is same
  R-Q=Q-T and R+T=50
  so, Q=25 but Question is (R - Q) = ? but we don't know the age of R.
  so answer is D data inadequate.
