The question is as follows,
In the Land of Liars there are exactly three Clans. Black clansmen always tell lies. White clansmen always speak the truth. Red clansmen are sometimes truthful. A,B and C are three people from the Clans Black,White and Red not necessarily in the given order.D is a clansman from the land of Liars.They were asked what their clans were and then what clan D is from. Their responses were,
A. I am not a white ;D is a black
B. I am not a black ;D is a Red
C. I am not read; D is a white
D. I am not a black; I am a white
Which of the following can be concluded?
1) D is a red
2) D is a white and C is red
3) A is red , B is a black , C is a white and D is a white
4) C is a white and D is a red
5) B is red
I think the answer is 3. A cannot be white. Also A has to be telling the truth in his first question always. So A is either Black or Red.
But the rest seem impossible to analyze. Is my answer correct and how do I solve this sort of a question quickly?
