The inhabitants of an island are either gentlemen or liars. A gentlemen always tells the truth and a liar always lies. A, B and C are three of the inhabitants. A sailor who landed on the island asked A, "Are you a gentleman or a liar?" A answered but the sailor did not hear clearly what A said. He asked B, "What did A say?" and B replied, "A said that he is a liar." C then shouted, "B is lying!" 1. It is impossible to tell whether A is a gentleman or a liar. 2. B is a gentleman and C is a liar. 3. B is a liar and C is a gentleman. Which statements are correct?

    consider C is L =>B is G => A said "i am a liar" this is impossible since if A is a liar then he told the truth and if A is a gentleman then he just lied so the only other case is that C is G => B is L => A did not say "i am a liar"

    yes 3 is correct... but what about statement 1 ? i think it is also correct because A can be either a liar or a gentleman

    I agree with hoblos; Because B is a liar, a statement made by B against A cannot be taken as proof for whether A is a liar or a gentleman.

    yeah and the question is "Which statementS ARE correct" so there could be more than one

    but if B lied and A did not say "i am a liar" and still answered the sailors question A must be a gentleman

    A said " im a gentleman" but he may be lying !! so both cases are possible

    if b is a liar then it is impossible to determine A i believe..so that means b is a gentleman..but if he is then A said he was lying..which would be impossible as well because like you said liars wont admit that and gentlemen wont say that

    From the problem its difficult to find the validity of both b's and c's statement. So I'll go with the 1st.
