Detailed Solution for RRB Group D Mock Test - 40 - Question 98

C is 10 years older than B. Therefore, the ages of C and B can be (16,6) or (21,11) in that order. 
A is older than B but younger than F. 
C is older than F.

If the age of B is 11, then the age of A must be 16, the age of F must be 17 and age of C must be 21. However, it has been given that C is not 17 years old and hence, we can eliminate this condition.

Therefore, B must be 6 years old, A must be 8 years old, F must be 11 years old and C must be 16 years old. D is not the oldest person. Therefore, D must be 17 years old and E must be 21 years old.

Difference between the ages of A and E = 21 - 8 = 13 years. Therefore, option C is the right answer.
