6月JJ第214题

edmund_zh

214   有L, M, N三人, 在一月份分别投了1000, 1200, 2000元钱在一投资上. 年底按每人总的投入按比例分红. 问M分了多少.

        A:M 中间又追加两次投资，每次200， L追加了一次，N 没有追加。

        B：总收益是 500

(数字是我虚拟的)

我选E.

奇怪，B不是可以直接推出M的收益么？

这道题是不是应该选c啊，如果只有b不知道中间变动还是不能推出分红啊

edmund_zh

我觉得暗示中间没有变化吧，见仁见智

B可以直接出来了...

考虑第二个条件的时候不要对第一个条件念念不忘.....

当第二个条件不能够单独出来的时候再考虑两个条件比翼双飞一下....

Problem stem:

Dividend will be given on the total investment at the end of the year.

Here initial investment is given.

Stem1:

M's total investment = 1200+200+200=1400

L's total investment = 1000+ X (unknown value).

N's investment = 2000.

NOT sufficient for two reasons:- (1) L's total investment is not known (2) Total dividend is not known.

Stem2:

Tota dividend is given but the year end proportion is not given. NOT SUFF.

1+2: We have total but the proportion is not ok. NOT SUFF.

Answer should be E.

希望，帮助
