Figure out "Who ate the Pizza?" and explain the answer
The Puzzle: Five roommates, Abe, Bob, Carl, Dave, and Ziggy, share an off-campus apartment. On Monday night they had leftover pizza and so they put it in the refrigerator. On Tuesday when Ziggy went to get some of that pizza he found that it had all been eaten. Later Ziggy confronted his four roommates to find out who ate the pizza. Each roommate made one statement. The person who ate the pizza lied; his statement is false. The other three statements are true. Which one ate the pizza? Here are their four statements:
Abe: I was in class all day.
Bob: Carl ate the pizza.
Carl: Bob's statement is false.
David: Carl's statement is true.
What will be an ideal response
If David is lying, then what Carl said must be false. And that makes two statements false. But only one statement can be false. So what David said is true. If David is telling the truth, then, as he says, so is Carl. And if Carl is telling the truth, then Bob must be the person who lied. Bob said that Carl ate the pizza, and if that is a lie, then Carl is innocent. That leaves us three possibilities, Abe, Bob, and David. The puzzle says that the person who ate the pizza is the person who lied. So it was Bob.
