Prisoners Hat Riddle Answer:
Now you know the answer to Black and White Hat Riddle. You may be wondering how this is possible to guess the color without looking the other persons hat color. To answer this question, I have explained the step-by-step process down below:
We know that the prisoner is allowed to shout the color of hat as soon as they know their color.
Men 1 can see both 2nd and the 3rd person. Suppose they both (2nd and 3rd) have the same color hat then it becomes easy for the men 1 to know that what color he is wearing because there are only 2 black and 2 white.
If the men 2 and men 3 has different color then it is impossible for the 1st men to tell the color of its hat.
Due to the silence of the men 1, the men 2 can interpret that he is not able to guess the color because he (2 men) and the 3rd men is wearing different color.
So, the 2 men is sure that he is wearing different color then men 3 and he can tell the color by looking at the color of the 3 men hat.
