You are on an island and you meet three people, Jeswin, Parker and Crasbo. You know that they are either liars, knights or knaves (someone who alternates between truth and lie). They have a strange religion - for one half of the year they talk in English and for the other half they talk Gambalidarian (their language). Naturally, you arrive during the latter part of the year. You know that if you ask them what they are, they either say 'Blarg', 'Grot' or 'Cloysta', but you don't know which means what out of liar knight and knave. You also know that 'Jappa' means 'is a' and 'Bokka' means 'I am a'. They give the following statements:
Jeswin : Bokka Grot. Parker Jappa Cloysta.
Parker : Bokka Blarg. Crasbo Jappa Blarg.
Crasbo : Bokka Grot. Jeswin Jappa Cloysta.
What does Blarg, Grot and Cloysta mean in English, and what are each of the people?
I've never seen a problem with knaves in it before. From the solution given, I'll assume that it's understood that knaves always begin by telling a truth. However, that's not made clear in the problem. (It says they alternate, but makes no assertion as to what they begin with.) In the case of a knave that can begin by lying, the following is also a possible solution:
Grot = Knight
Cloysta = Knave
Blerg = Liar
Jeswin (Knight) = TT
Parker (Knave) = LT
Crasbo (Liar) = LL
You might want to be a little more specific in the definition of a knave, for those of us who haven't seen the term before. =)
