4 Criminals Puzzle!!!

4 criminals 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 criminals are lined up on some steps (shown in

 picture). 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 criminals are 


wearing hats. They are told that there are two white 


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


what color 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 color 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?

Answer:

If both Man 2, Man 3 have same hat color. Man 1 


shouts opposite color to that of Man 2 and Man 3. If 


Man 2, Man 3 have different hat color. Man 1 is quiet. 


So Man 2, shouts opposite color to that of Man 3!
