3 Non-ABAP Puzzles - Solution

[ABAP Spirit]

Logic Puzzle: 

There are three people (Alex, Ben and Cody), one of whom is a knight, one a knave, and one a spy. The knight always tells the truth, the knave always lies, and the spy can either lie or tell the truth.

Alex says: “Cody is a knave.”
Ben says: “Alex is a knight.”
Cody says: “I am the spy.”

Who is the knight, who the knave, and who the spy?


  • We know Ben isn’t telling the truth because if he was, there would be two knights; so Ben could be either the knave or the spy.
  • Cody also can’t be the knight, because then his statement would be a lie.
  • So that must mean Alex is the knight.
  • Ben, therefore, must be the spy, since the spy sometimes tells the truth;
  • leaving Cody as the knave.
