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 choice from the following options
A) 1 year
B) 2 year
C) 25 year
D) Data inadequate
E) None
Solution   R - Q = R - T	Q = T.   Also,	R + T = 50   ‹=› R + Q = 50.   So, (R - Q) cannot be determined.   Answer Data inadequate
