I'm new to this list, so I can't tell if you're serious or not, but it goes something like this:

A's age = 10 a1 + a2    same for other ages; m is middle number

omitted age = 100 (d1-a1) + c2 - b2        d1 not = a1

therefore d1 - a1 = 1        then [omitted age] c1 or b1 must be 9

try c1 = 9 and d1 = 2 and a1 = 1

this leads to 11 b1 + b2 = 71 + 10 m

only combo that works is 6, 5 and 0
