A batch of parts was originally planned to be distributed to masters and apprentices for processing at a ratio of 5:3. Now the master processes 120 parts, which is more than 20% of the assigned tasks, while the apprentice only completes 60% of the tasks assigned by him, how many parts does the apprentice actually process?
一批零件，原计划按5：3分配给师徒加工．现师傅加工120个，超过所分配任务的20%，而徒弟因事只完成他所分配任务的60%，徒弟实际加工零件多少个？
