Mrs. Stotch is a fifth grade teacher. One of her students took her apple. Mrs. Stotch has narrowed the suspects down to Billy, Paige, and Tyler. Each of the students give these statements:
Billy: I didn’t do it.
Paige: I didn’t do it.
Tyler: Paige did it!
Mrs. Stotch knows that only one of the kids is telling the truth. Who is telling the truth and who took the apple?
Billy did it. Paige is telling the truth so she didn’t do it. Tyler is lying so he reinforces that Paige didn’t do it. Billy is lying so he did it.
