Four friends: Dave, Mike, John, and Terry, are nicknamed Stick, Batman, Atomic Head, and Feaser, but not in that order. Which friend has which nickname?
A. John is faster than Batman but not as strong as Atomic Head.
B. Batman is stronger than Terry but slower than Feaser.
C. Dave is faster than both Stick and John, but not as strong as Batman
Strength and speed are independent qualities.
(from Terry Stickels)
By statements A and C, we know that John is not: Batman, Atomic Head, nor Stick, therefore, he is Feaser.
By statement C, we see that Dave is not: Stick nor Batman, and John is Feaser, therefore, by the process of illimination, Dave is Atomic Head.
Now we have Mike and Terry, to be Batman or Stick, in some order. By statement B, Terry is neither Batman nor Feaser, and Atomic Head is Dave, therefore Terry can only be Stick.
The only one left is Mike, who can only be Batman.
