229. Of the three residents K, M, and P of a remote area, one is a truth-teller, another is a liar, and the third is a trickster. They made the following statements:

K: I am a trickster.

M: That's true.

P: I am not a trickster.

Who are K, M, and P in reality?
$\triangle$ Let's start with K. He cannot be a truth-teller due to his statement. Let's consider two cases.

1) Suppose $\mathrm{K}$ is a trickster. Then $\mathrm{M}$ is a truth-teller based on his statement, which means $\mathrm{P}$ is a liar. But in this case, $\mathrm{P}$'s statement is true, which is impossible.
2) Suppose $\mathrm{K}$ is a liar. Since M's statement turned out to be false, M is a trickster. Therefore, P is a truth-teller, which corresponds to the truthfulness of his statement.

Answer: $\mathrm{K}$ is a liar, M is a trickster, $\mathrm{P}$ is a truth-teller.
