A and B process parts at the same time, and A gets twice as many tasks as B. After A completes (1/3), B still has 63 unfinished parts. At this time, A improves the technology and improves the efficiency ( 1/4), so that (3/4) of the remaining tasks are completed, B still has (3/8) of his total tasks left unfinished, when both A and B have completed the tasks, how much did they do parts?
甲、乙两人同时加工零件，甲分得的任务为乙的2倍，当甲做完(1/3)后，乙还剩63个没做完，这时甲改进技术，效率提高了(1/4)，这样又完成剩下任务的(3/4)时，乙还剩下他总任务的(3/8)没有完成，当甲、乙都完成任务时，两人一共做了多少个零件？
