I'm quite confused on how to proceed with this question.
Knights always tell the truth, and knaves lie.
You meet two people, A and B. A says, “I'm a knight
and he's a knave.” B says, “I agree.” What are they?
I'm not sure what to do with B's statement. Since B is a knave, he disagrees with the statement? Is that it?
Best Answer
They are two knaves, I mean all other options are clearly false.
Since B agrees with the statement, both are claiming that A is truthful and B is contrary.
However if that claim were true, then B would not agree. So the claim must be false, which means both A and B must be lying.
That is, both are knaves.
