Have you checked the BPP website to make sure that they haven't issued an amendment to either the question or answer (they update these as printing errors are discovered)? If that is the exact question you have copied then I would agree that the cost appears to increase by £105.60 every month hence I would agree with your answers. Unless I'm missing something really obvious?? I'm assuming the reference to IA54 is an error as you've typed IA53 everywhere else?
