Whose age was omitted from (b) down, and what are the ages of the 4 women ?Note: this can be solved by hand. Those who will use the computer, give the others some time before posting the solution obtained this way. Tk you.

re(3): Re: Solution by hand by pcbouhid)
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 (d1a1) + 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
