OK folks, it looks like the thread is winding down. Time to bring forth some "acurate" Comparisons. I thought at first that I'd just provide you all with the way "I know" that works 100% of the time to determine which one of the 12 Bullets is different and if it is heavier or if it is lighter. Then I looked at some of the answers and decided that some of you may(?) know a better way.



So, what I'm going to do is ask those of you who can do it in either "one" or "two" Comparisons to let the rest of us in on how you did it. Maybe I can learn something here.



...



Here is the set-up:



A Double Pan Scale -> ____________________ ^ ____________________



12 Bullets -> 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12



...



One of the above Bullets is either Heavier or Lighter. For those of you who can show me how to determine which one it is and if it is Heavier or Lighter in "one" or "two" Comparisons, I'd appreciate it. Your method must work 100% of the time for any of the 12 Bullets.



If anyone sees a problem with their "Logic" before I get back on line, please jump in and ask them to explain what you see as a problem.



By the way, thanks to all of you folks who jumped in. I had a lot of fun messing with this Logic Problem the first time I saw it and I hope you did too.
