Arm Appraisal III (Posted on 2012-12-21) Difficulty: 2 of 5
A distant planet is inhabited by creatures having more than two arms. The ones with an even number of arms are the knights who always tell the truth; the ones with an odd number of arms are the liars who always speak falsely.

Four inhabitants are conversing amongst themselves:
  • The green one says, "I have ten arms. The blue one has only eight arms."
  • The blue one says, "I have ten arms. The green one has nine arms."
  • The red one says, "The blue one has ten arms. I have eleven arms."
  • The striped one says, "None of the four of us except myself have ten arms."
Which of the four inhabitants has exactly ten arms?
