Black or white?
Three men A, B and C are captured by cannibals. They are tied to stakes. A can see B and C. B can only see C. C can’t see either A or B. They are then shown five hats. Three are black and two are white. The men are then blindfolded. A hat is put on each one’s head, the remaining two hats are hidden away and then the blindfolds are removed. They are told that if one of them can call out the colour of his own hat, they can all go free, otherwise they’ll really be in hot water. \they are not allowed to confer.
After a short time A calls out, “I don’t know my hat colour”. Soon B calls out, “I don’t know my hat colour either”. C thens called out the colour of his hat.
What colour is C’s hat?
