Population puzzle

[Peter M. Brigham]

I haven't tried to actually write script for this, but it occurs to me that you could first find all the sets of numbers whose last digits add up to a multiple of 10 (or whose last 2 digits add up to a multiple of 100, etc), then iterate through a much smaller group of sets to test for their total sum.

You all may not have a logic based approach, but at least you got a solution.   Right now the straight forward approach with some randomness thrown in looks pretty good to me!
