Ah, that's a good solution, Carol! I didn't notice that before. I like that one better 'cause it can occasionally result in using only two weighings, so it's more efficient.
I got PhD. at 80-something percent. I'm couldn't find the button to print out my certificate, though. Oh well, maybe it's just an honorary doctorate or something like that.
My first post here, so hey everyone. I'm a big fan of Sherlock (which you could probably deduce by my presence here). I just wanted to post a couple of interesting logic puzzles I found. I was looking for some challenging logic puzzles to test my deductive reasoning abilities. They are new to me, but maybe not to some of you.
Here's one.
Here's the other (slightly harder).
If anyone knows any there logic puzzles, let me know! I love these things.
