Five men, A, B, C, D, D, E are wearing caps of block or white colour without each knowing the colour of his cap. It is known that a man wearing black cap always speaks the truth while the ones wearing white always tell lies. If they make the following statements, find the colour worn by each of them: A : I see three black caps and one white cap. B : I see four white caps C : I see one black cap and three white caps D : I see your four black caps.

A: "3 truthars, 1 liar" B: "4 liars" C: "1 truthar, 3 liars" D: "4 truthars" Now, if D were telling the truth everyone else would have to be telling the truth, yet B says he sees 4 liars and A says he sees only one. These contradict each other. D is lying. A says that D is the only liar, based on this information. However, B says there are 4 liars and C says there are 3. A must be lying, because if we assumed A were telling the truth then B and C would be right and A would be a liar anyway. A is lying C's statement contradicts B's (because if B's is true everyone else is lying). Both of them say that A and D are lying. If B sees 4 liars, then C must see 3 liars and 1 truthar (B). C's statement is therefore true, which proves that B does not see 4 liars. B is lying. C is telling the truth. A, B, and D are lying. C sees three liars. Therefore, E is telling the truth.
