the number of boxes loaded by worker( night crew) =3/4 number of

boxes loaded by worker (day crew)
the number of workers in night crew=4/5 number of workers in day

crew

number of boxes loaded per worker(day):b
number of workers(day): w

wb  /   (3/4 b*4/5w)+wb=5/8

楼上解法很对。
黄色部分的意思是说，我就直接最通俗的说了啊。在装货码头上，每个上晚班人装货的数量是上白班的人的四分之三。如果晚上上班的人总数是白天上班四分之五，BALBALABALA.。
