eldest son age = a
elder son age = b
youngest son age = c
according to given conditions
b+a = 15 OR b+c=15
and
a-b = 3, b-c = 2, OR a-b = 2, b-c = 3
there are 4 combination
1) a+b = 15, a-b = 3, b-c = 2 (9,6,4)
2) a+b = 15, a-b = 2, b-c = 3 (8.5,6.5,3.5)
3) b+c = 15, a-b = 3, b-c = 2 (11.5,8.5,6.5)
4) b+c = 15, a-b = 2, b-c = 3 (11,9,6)
