Mr Linton, the science teacher, gives out scores for the written exam and the practical experiment exam. These two scores are then totalled together to provide an overall mark. |
Maya and Sarah received the same overall marks for the end of term exams for Science.
Maya: “If I received 40 marks in the practical experiment and you received 40 marks in the practical experiment, that means our written exams must also have been the same marks!”
Sarah: “If our written exam marks were different, then our practical experiment marks must also have been different.”
