Three convicts are brought into the warden's office. He says
he can parole one of them and to decide which one he will
parole he takes out 5 hats (3 red and 2 white). He stands
behind them and places a hat on each one of their heads and
puts the other two remaining hats in a drawer.
He tells the prisioners they can look at the others hats and
if they can tell which hat they have on they will be the one
who is paroled.
The first man looks at the other two and says, "I don't know."
The second man looks at the others hats and says, "I don't
know."
The third man who is blind says, "Even though I have not the
gift of sight I can tell by what the others have said that
the color of my hat is..."
What color is the blind mans hat and how does he know?

Answer Posted / anurag
Let the three be A, B , C
1. A sees the other two as either Two Red or One Red and One White
2. B knows that B's and C's Hats are as in #1. Had C been White B would have
surely said his Hat is Red. Hence by contradiction C is Red.
