perplexus.info :: Logic : Black and white hats

Black and white hats (Posted on 2006-06-15)

Six logicians stand one behind the other facing an opaque wall such that 2 are on one side and 4 are on the other. None of the logicians can turn around or see beyond the wall.

Each wears a black or white hat as shown below; "|" represents the wall, capital letters are used to identify the logicians, and "b" and "w" refer to black and white respectively.

b   w   |   b   w   b   w 
A   B   |   C   D   E   F

Each knows the location of the others and the quantity of each colour of hat. Who will be first to declare having which colour?
