Assignment:
Somebody ate the sausages!
Superman, The Flash, The Green Lantern, Batman, and Wonder Woman went out to lunch. Wonder Woman went to the ladies room just before the meal was brought out by the waiter. When she returned everyone had their food, but all of her sausage was missing from her plate. Wonder Woman loves sausage, so she asks the others who took her sausage. Here's what these four boys have to say:
Superman: "Batman ate the sausage!"
Batman: "Green Lantern ate it all up!"
Flash: "I didn't eat them, no way!"
Green Lantern: "Batman's totally lying!"
Only one of these rascals is telling the truth and all the others are, needless to say, lying. Can you figure out who ate the sausage?
Provide complete and step by step solution for the question and show calculations and use formulas.
