Knowing the Natives (Posted on 2003-08-16) Difficulty: 2 of 5
I met two natives on an island - Benny and Lenny. They are either a knight, a liar or a knave. Knights always tell the truth, liars always lie and knaves alternate between truth and lie. They tell me this:

Benny : We are both of the same type.
Lenny : I am a knave.
Benny : Lenny is a liar.

A knight then tells me what Lenny is. From this I was able to work out what they were.

What are Benny and Lenny?

The visitor was told that Lenny is a liar and he deduced that Benny is a knight.
