Q21:

k, n, 12, 6, 17

What is the value of n in the list above?

(1) k < n

(2) The median of the numbers in the list is 10.

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

I think the answer should be E. Anyone agree with me?

呵呵，条件2告诉你K，N中一个是10，但是求中数要排序的，现在不知道K，N谁大，知道了排个序就可以定了，条件1告诉你K〈N，那么排序的结果是6，K，N，12，17 OR K，6，N，12，17，OR K，N，6，12，17就这3个情况了吧，注意最后的一种情况，那个时候的中数是6，和题目给的比一样，那么不存在，前2种的结果都可以给出，N就是这个中数，等于10。
