A and B process the same number of parts at the same time. A has completed (1/4) of it, but B has 45 parts left unfinished. At this time, A's efficiency has increased by 20%, and when A has done the rest (2/3), B still has (1/3) of his original work to do, ask: What is the total work of the two?
甲、乙两人同时分别加工同样多的一种零件，甲做了它的(1/4)，而乙还有45个没做，这时甲效率提高了20%，则当甲做了余下的(2/3)时，乙还有他原工作总量的(1/3)没做，问：两人的总工作量是多少？
