Prisoners and hats puzzles: differnt

4 prisoners are caught and are to be punished. The Judge allows them

to be freed if they can solve a puzzle.

If they do not, they will be hung. They agreed.

The 4 prisoners are lined up on some steps (shown above). They are

all facing in the same direction. A wall separates the fourth man

from the other three.

So to summarize:-

Man 1 can see men 2 and 3.

Man 2 can see man 3.

Man 3 can see none of the others.

Man 4 can see none of the others.

The prisoners are wearing hats. They are told that there are two white

hats and two black hats. The men initially don't know what colour

hat they are wearing. They are told to shout out the color of the hat

that they are wearing as soon as they know for certain what colour

it is.

They are not allowed to turn round or move.

They are not allowed to talk to each other.

They are not allowed to take their hats off. Who is the first person

to shout out and why?

clich on the title for solution........








Solution: Man 2

bcoz 3 and 4 can not shout....

and Man 2 can see that 3rd is wearing black.... so if color of his hat was also black 

then Man 1 should have shouted that he(man 1) is wearing white as we have only 2 black hats..... 

as man 1 did not shout so man 2 interpret that he is not wearing black and then he says its white
