উত্তর:
Data inadequate
Hints: Given that,
1. The difference between R and Q = The difference of age between Q and T
2. Sum of age of R and T is So l.C [RTT = 50]
Question : R - Q = ?
R - Q = Q - T
(R + T) = 2Q
Now given that, RTT = 50
So, 50 = 2Q and Q = 25
Question is R - Q = ?
Here we know the age of Q, but not of R
There for R - G can not be determined.
