请问携隐13套与GWD题号如何对应?
携隐后面几套好像都是打乱顺序的GWD,这样看总结贴的时候根本找不到,大家有什么好方法?
谢谢!
但是XY的数学题里面没有对应的GWD题号,我有几道题实在是不明白,搜索也找不到,比如下面这题:
Is the number of members of Club X greater than the number of members of Club Y ?
(1) Of the members of Club X, 20 percent are also members of Club Y.
(2) Of the members of Club Y, 30 percent are also members of Club X.
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.
答案是C,但我认为是E。
假设:
X=100,Y=110,则20 percent of X 是20 < Y,30 percent of Y 是33 < X;
同样的,假设:
X=110,Y=100,则20 percent of X 是22 < Y,30 percent of Y 是30< X;
应该是不能判断的,为什么选C?
那位能够指点一下,谢谢!
谢谢!
如果重复的人数是X、Y唯一的交集,我同意。
但,如不是唯一的交集,比如只是重复人数重的一部分,应该选E,我从题目看不出重复的人数是唯一的交集。也许是翻译的时候不严谨吧。
不过无所谓,明白了就好。
xy是什么?
