The "classic" counterfiet coin puzzle
April 11, 2010 at 10:41 pm

The basic puzzle had 12 coins, one of which differed in weight from the others, - to be found using a two pan balance just three times. Most solutions utilized labeling of some kind. For that reason I suggest the puzzle be expanded to a point whereby it is not practical to label them - such as 120 coins / five weighings. this version is only two steps longer, and still very simple to solve mentally (without paper and pencil)

I'm not saying that there aren't many intelligent members here, but why would you think that this forum was for intelligent people only? I hate to say it, but being an atheist doesn't make a person intelligent and as far as I know, this is atheistforums.org, not intelligentmemgers.org

And why would you think intelligent people would waste their time doing math homework?

Why would anyone label, this has a very simple solution, one you don't even need a pencil or paper!
