Answer:D
Q is the same age as R and the same age as T. What is the exact age difference between R and Q if the total of R and T's ages is 50 years?
A. 1 year B. 2 years C. 25 years D. Data inadequate
Explanation: 1. The age difference between R and Q equals the age difference between Q and T.2. The sum of R and T's ages is 50, i.e. (R + T) = 50.R - Q =? is the question.,Q - T = R - Q.2Q = (R + T).As a result, (R + T) = 50.As a result, 50 = 2Q, and Q = 25.(R - Q) =? is the question.We know the value(age) of Q (25), but we have no idea how old R is.As a result, (R-Q) cannot be calculated.
