Did Insurance Company K have more than $300 million in total net profits last year?
(1) Last year Company K paid out $0.95 in claims for every dollar of premiums collected.
(2) Last year Company K earned a total of $150 million in profits from the investment of accumulated surplus premiums from previous years.
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 statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
题目分析：
问公司K去年是否有超过3亿美元的净利润。条件（1）和（2）给出了收取保费和支付索赔的利润以及累计盈余溢价投资产生的利润，但不能得知是否有其他收入来源或其他类型的费用。因此，不能计算净利润。
因此，本题答案为（E），两个条件结合起来也不能解题，必须提供新数据。
这是道CR题
2、只是说出了用之前累积的剩余保费去投资，赚了150的profits。过关于保险的单词不熟悉，使得做题速度下降。in claims 索赔，premium保费，surplus剩余的。
逻辑就是：之前年份的premium collect来用来投资，今年的premium会有一部分索赔(claim)，是investment income+一部分expense，这怎么能得出net profit?
from GMAT GMAT CLUB Forum
Statement #2: this tells about the "investment of accumulated surplus premiums from previous years." Presumably, this company also sold some new premiums last year. Thus, the total revenue from premiums is unknown
have no way to know the full dollar amount of premiums last year, and even if we did know this, we would know the dollar amount paid out in claims, but we wouldn't know the other expenses that would cut into profit.
Answer = (E)
题意需要理解！
B 意思是这是由于多年来积累的盈余溢价所带来的利润。所以跟保费一点关系都没有。合在一起就不可以了。
如果问题是net profit是多少，答案会不会不同？
2、只是说出了用之前累积的剩余保费去投资，赚了150的profits。虽然题没做错，不过关于保险的单词不熟悉，使得做题速度下降。in claims 索赔，premium保费，surplus剩余的。
做错了选了b。个人理解。如果按照答案理解：（2）的说法错的原因是它并没有说出k公司去年total net profit。而是玩了一个文字游戏，说的是投资和premium的total profit。文中并未说“投资和premium就是k公司的total net profit”。这是个人理解，不知道对不对？
