In a puzzle involving four men buried up to their necks and unable to move, the challenge is for one to determine their hat color. The arrangement includes a brick wall between two individuals, A and B, preventing them from seeing each other's hat. The solution relies on the visibility of colors between C and D, leading C to deduce their own hat color based on the situational clues.

1. 4 Men in Hats

2. Puzzle Question:
There are 4 people (A,B,C,D) buried upto the neck. They can’t
move and can only look forward. Between A and B, there is a
brick wall. All of them were wearing hats either Black or
White (Total 2 Black & 2 White). In order to avoid from being
shot, one of them has to tell the hat colour, that he is wearing
in 10 min?
• They can’t move, talk, and can see only the front side only.

3. • A and B can’t see the each others, as there is a brick wall
between them. Therefore A and B can’t tell the colour of the
hats.
• And also if B and C wears same colour hat, either white or
black , then D will be able to tell the colour of the hats ( as if B
and C wears white hats, then A and D wears black hats. )
• If C comes to know that D can’t answer , then C will come to
know that B and C are wearing different colour hats. As C able
to see B’s hat, then he can tell the colour of the hat that he is
wearing.
