How Many Liars? - One. Since the finned Martian did indicate
that he was a truth-teller, then the Martian with feathered
ears was obviously telling the truth and must be a truth
teller. If the finned Martian was lying, then the horned
Martian was a truth-teller. If the finned Martian was a
truth-teller, then the horned Martian was a liar. So, no
matter how you look at it, two of the three Martians were
truth-tellers and one was a liar.
