Average age of A & B is 24 years, therefore their sum = 48 yrs
:
average of B, C & D is 22 years, therefore their sum = 66 yrs
Assume B = 23 yrs old,
:
The sum of the ages A, B, C & D is:
:
Ensure that A + B add up to 48
Ensure that B + C + D add up to 66
:
25 + 23 + 22 + 21 = 91
:
Assume that B = 25 yrs old then
23 + 25 + 20 + 21 = 89
;
I don't think there is a unique solution
