Brain Gymnastics 1
I don’t know who created, devised this puzzle:
There’re three men standing in line one behind the other, A in front, B in the middle and C behind. They know that there are three white and two black hats. Each one is wearing one of these hats, but no one knows or can see his own hat.
C can see B and A wearing their hats.
B can only see A’s hat as he can’t see behind him.
A can’t see what C and B are wearing as he can’t see behind him either.
No one knows the colors of the two remaining hats that’s left.
When first C was asked what color his hat was, he answered “I don’t know.”
Then B was asked. He also said “I don’t know.”
Yet when A was asked afterwards, who couldn’t see any hat at all, he said, “I know the color of my hat.” How could he know it? Could you reveal this?
