When completed, the crossnumber below will have one digit (from 09) in each cell, and no zeros in row (a) and in column (a).
(a) (b) (c)

Cynthia´s age, and
Darlene´s age.
(c) Blanche´s age.
DOWN : (a) Darlene´s age
(b) Sum of three of the ages in (b) across.
(c) Cynthia´s age.
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.
(In reply to
re(6): Re: Solution by hand by Mike)
Mike, you are in the right way.
Call the cells A, B, C, D, E, F, G, and test the 4 possible hypotheses, that are: (1) if Abigail´s age omited; (2) if ....
The sum of the 4 ages are : CDE
Hyp (1)  Abigail´s age omitted: CDE = ADG + AB
etc...
Only one hypothesis will remain.
