DS：telephone station has x processors, each of which can process a maximum of y calls at any particular time, where x and y are positive integers. If 500 calls are sent to the station at a particular time, can the station process all of the calls?

(1) x = 600
(2) 100 < y < 200

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statement TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.

想请教一下这题是不是选a？
由于太简单，我有点怀疑自己是不是漏掉了什么。。。A中不就是600>500 所以充分，然后B中的100<y<200，由于不知道processor的数，就不充分。
思路没吧？？求确认，谢啦

capability=Qty. of machines x efficiency per machine x period 注意标黄部分，每个处理器可以处理Y个，所以必须和X·Y的值有关系，时间见后面两个标黄的，应该可以被认为是同一个定量，所以我觉得只能是C。

x*y的公式没错，但条件1，有600个processor， call只有500个，所以一定是能处理掉的（processor还有多于100个），不是么？所以还是选a
对吧？

对哦，应该是A，题干里隐含条件X>=1,Y>=1
