 Liars Logic (Posted on 2014-03-13)
You find yourself on the Island of Knights, Knaves and Liars, where a race has just finished. Each of the five participants, who are all different ages, is either a Knight (who always tells the truth), a Liar (who always lies), or a Knave (who alternates between true and false statements, though their first statement may be either true or false).

Each of the five competitors makes the following statements to you. Figure out their type (Knight, Knave, or Liar), their relative ages, and the order in which they finished the race.

Bart is a Liar.
Earl is a Liar.
I'm younger than Bart.
The oldest person came in 4th place.

Bart says:

I'm older than Dave.
The 5th oldest person came in 3rd place.

Dave is a Liar.
Bart is a Liar.
I'm older than Earl.
I'm younger than Dave.
The 4th oldest person came in 1st place.

Dave says:

Earl is a Liar.
I'm younger than Earl.
The 3rd oldest person came in 2nd place.

Earl says:

Dave is a Liar.
I'm older than Bart.
The 2nd oldest person came in 5th place.
