天山 4-Q5 math

A department manager distributed a number of pens, pencils, and pads among the staff in the department, with each staf member, receiving x pens, y pencils, and z pads. How many staff members were in the department?

(1) The members of pens, pencils and pads that each staff member received were in the ratio 2:3:4, respectively.

(2) The manager distributed a total of 18 pads, 27 pencils and 36 pads.

ANS:E

我選的是C..為什麼不對了..是不是又陋了哪各偵結點呢

是呀,条件1 给出的是MEMBER的拥有的东东的比率2:3:4, 他们实际拥有的数量可以是这个比例的倍数, 只要能满足a total of 18 pads, 27 pencils and 36 pads就行了.  比如说可能是3个MEMBER,每个人拥有6pads,9pencils,12pads

休息之前再给出个人意见，mm说的是可能的人数，而文中的问题是具体是多少个人（how many，而没有问possible），按照给出两者条件的结合，人数应该（1，9）之间，那么就有多种选择，你可以说只有一个成员，也可以说有9个，或者其他的，那么答案是不定的，从而只能选择E了；

謝謝,,我了解了,,,

唉,,欠缺考慮,,敗點之ㄧ

只能是3个MEMBER啊！

请赐教

从1到9都是可能的。
