Q10:

Was the average (arithmetic mean) weight of the package mailed at a certain post office yesterday greater than 600 grams?

(1)   The total weight of the packages mailed at the post office yesterday was greater than 14,500 grams.

(2)     Fewer than 25 packages were mailed at the post office yesterday.

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.

Answer: C

WHY NOT E？

I picked up E as well

答案是C，刚才我的机器上看不到讨论帖，我不得不先回一个才能看到讨论。所有...CD今天到底怎么拉，为什么必须要我回帖才能看到以往的讨论呢，在每个板块都是这样，晕倒

是e，因为fewer than 25即是小于25 所以package最多只能是24个。

14500/24大于600

你是说C么？

我居然也选了e...
