1) Adam says Bob lies
\n" ); document.write( "2) Bob says Charlie lies
\n" ); document.write( "3) Charlie says Adam and Bob both lie
\n" ); document.write( "
\n" ); document.write( "a) suppose Adam tells the truth, then Bob lies,
\n" ); document.write( " if Bob lies, then (2) Charlie tells the truth
\n" ); document.write( "
\n" ); document.write( "b) if Adam tells the truth, from (a) we got Charlie tells the truth,
\n" ); document.write( " then from (3) Adam should lie which contradict the hypothesis
\n" ); document.write( "
\n" ); document.write( "c) if Adam tells the truth, we got a contradiction, hence Adam lies
\n" ); document.write( "
\n" ); document.write( " if Adam lies then Bob tells the truth,
\n" ); document.write( " if Bob tells the truth, then Charlie lies,
\n" ); document.write( " if Charlie lies then either Adam or Bob should tell the truth
\n" ); document.write( " this is not contradicting, since Adam lies, but Bob tells the truth,
\n" ); document.write( "
\n" ); document.write( "hence Adam lies, Bob tells the truth and Charlie lies.
\n" ); document.write( "
\n" ); document.write( "
\n" );
