I think that Dave Wallis may have had the germ of the idea behind the
solution.  In his example, you know for that element of the set of
possible answers that the answer is "15".  This is a unique solution,
according to Dave.  Is there a house number that does not have a
unique "age of the children" solution.  I haven't done the
calculating, nor will I, but is it possible that the way that you
"cannot tell" is that there is an answer that is not unique, i.e. more
than one element of the answer solution is the house number.  I have
this feeling in my logic center that this is the road to the
solution.
