Know thy Knaves (Posted on 2007-10-09) Difficulty: 4 of 5
Alex, Bert, and Carl are taking a break from being main subjects in these logic puzzles, so Dave and Eddy decided to comment on the rarely seen Fred, Gary, and Hank.

Dave and Eddy are both knaves and each one makes four of the eight statements below. The statements are in order, but whether Dave or Eddy made any given statement is not known. Without knowing which statements are Dave's and which are Eddy's, can you determine the types of Fred, Gary, and Hank?
  1. Fred is a liar.
  2. Gary is a knave.
  3. Hank is a knight.
  4. Fred and Gary are the same type.
  5. Gary and Hank are different types.
  6. Fred is a knight.
  7. Hank is a knave.
  8. Gary is a liar.
