The master and the apprentice process a batch of parts together. The master does it for 6 days first, and then the apprentice does it for 3 days, then the task can be completed; if the master does it for 5 days first, and then the apprentice does it for 5 days, the task can also be completed. It is known that apprentices make 48 parts every day. So how many parts are there in total?
师徒两人共加工一批零件，师傅先做6天，再由徒弟做3天，则可完成任务；如果师傅先做5天，再由徒弟做5天也可以完成任务．已知徒弟每天做48个零件．那么这批零件共有多少个？
