Q5:
A department manager distributed a number of pens, pencils, and pads among the staff in the department, with each staff member receiving x pens, y pencils, and z pads.How many staff members were in the department ?

(1)The numbers 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 pens, 27 pencils, and 36 pads.



A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

正确答案是是E，我选的B，我是这样想的。人数和每个人分到的数量肯定是整数。
那么（2）中把数量分解，即：18=2*9.   27=3*9.    36=4*9 这样的话，肯定就是9个人啊。。。。
