Here's another hat-wearing puzzle which some of you may know. If you do, give the others some time to work it out.
Three guys apply for the job of Logician with the Wise Mens Club.
The Chief guru comes in and tells them the following:
"Here in my box I have five hats: three are black and two are white. I will now blindfold you and place a hat on each of your heads and put the other two back in the box. When I remove the blindfolds, each of you will see the other two hats, but not your own. Whoever deduces the colour of his own hat, can come into my office and explain how you figured it out. If you are right, the job is yours."
It should go without saying that there is no mirror in the room.
With that he blindfolded them and placed a black hat on each head. (What could be fairer than that?!)
When the blindfolds were removed, after about three minutes person A got up and explained to the Boss his thinking.
How did he reason??
(Sorry about the sexist imagery. But then, generally speaking, men are more logical than women ;-) )
I prefer this puzzle to the Four Hats one because here each one has an equal chance, and, this time round, definitely the best man wins. In the former, the middle guy had a clear advantage.
In peace
