Just Jauntily Jousting (Posted on 2005-08-15) Difficulty: 3 of 5
A Baron, a Count, a Duke and an Earl met at a jousting tournament. In the first round, two met in the first joust, and the other two met in the second joust; the two winners from the first round met at the second round for the final joust. After the jousting, they declared:

  • Baron: I beat the Earl.
  • Count: I faced both the Baron and the Duke.
  • Duke: I didn't make it past the first round.
  • Earl: At the first round, I lost to the Duke.
  • I knew how many were knights, and how many were liars (though not who was what) but that wasn't enough to know what jousts there had been.

    However, I happened to know that a certain joust had taken place (though I didn't know who won and if it had been in the first or the second round) and that allowed me to know every result.

    Can you deduce this?

    The speaker knew the Baron had jousted with the Duke, and that there were two knights and two liars.
