There is a batch of parts that were originally planned to be distributed to two masters and apprentices for processing according to the ratio of 8:5. The master actually processed 1,600 parts, which was more than 25% of the assigned task, and the apprentice only completed 60% of the assigned task due to something, how many parts did the apprentice actually process?
有一批零件，原计划按8：5分配给师徒两人加工．实际师傅加工了1600个，超过分配任务的25%，徒弟因有事只完成分配任务的60%，徒弟实际加工零件多少个？
