Is as much younger than as he is older than . If the sum of the ages of and is , what is the difference between and 's age?
Given that
Let the ages of Q, R and T are and respectively
The difference of ages between R and Q The difference of ages between Q and T
The sum of the age of R and T is
From equation and
Here we found the age of , but it's not possible to find the age of and
Therefore, cannot be determined as the given data is inadequate
