这样该不会涉及版权问题吧？如有侵权，望告知楼主，顺便告诉楼主怎么删帖，找了好半天。

楼主见这种有百分数的题就一脸蒙蔽啊，是不是要用数学公式啥的？做这种归纳题有啥套路没？望大神解答，楼主感激不尽。

According to a recent magazine article, of those office employees who typically work 8 hours at the office each day but sometimes say that they will work at home on a particular day, 25 percent actually work less than one hour. At the same time, over 90 percent of those same office employees believe they are more productive working at home than working in their office.

The statements above, if true, best support which of the following conclusions about the office employees discussed in the article?

		On average, the office employees working at home for a day work fewer hours than office employees working at the office.
		10 percent of the office employees are less productive working from home than working in their office.
		At least 15 percent of the office employees do not define productivity exclusively in terms of the number of hours worked.
		At least 25 percent of the office employees can complete the same amount of work in one hour at home as in 8 hours at the office.
		Some of the office employees make statements regarding their productivity that are not in fact true.

if in a tennis tournament, a match reaches a fifth-set tiebreak, the lower-ranked player always loses the tiebreak (and, therefore, the match).  If Rafael, the second-ranked player, wins a tournament by beating Roger, the top-ranked player, then the match must not have included a fifth-set tiebreak.

Which of the following arguments most closely mimics the reasoning used in the above argument?

		If a woman with a family history of twins gets pregnant three times, she will have one set of twins.  Jennifer, who falls into this category, had two sets of twins, so she must not have gotten pregnant exactly three times.
		If a salesman sells more product than anyone else in a calendar year, then he will earn an all-expenses-paid vacation.  Joe earned an all-expense-paid vacation, so he must have sold more product than anyone else for the year.
		A newspaper can charge a 50% premium for ads if its circulation surpasses 100,000; if the circulation does not pass 100,000, therefore, the newspaper can't charge any kind of premium for ads.
		If a student is in the top 10% of her class, she will earn a college scholarship.  Anna is not in the top 10% of her class, so she will not earn a scholarship.
		All of the players on a football team receive a cash bonus if the team wins the Super Bowl.  If quarterback Tom Brady earned a cash bonus last year, he must have been a member of the winning Super Bowl team.

归纳题的解题方法：

1/找题干中各种信息的交集
2/题干的rephrase

这里第一题，先不看百分比我们可以得出的结论是：工作效率和时间是有关系的且是反相关；其实得出这个结论后5个选项里就只有C是对的

然后来处理一下百分比问题，设这个公司有100人，90人说他们在家工作更加有效率；25个人在家工作的时间比在办公室工作时间短也就是说更加有效率；90+25=115 个人claim 在家工作效率更加高，说到这里楼主应该明白了吧，其实就是个韦恩图啊，15个人是overlapped 所以就是15% 啦

第二题：是个类比的题型：
题目给出了一个general rule, 然后陈述了一个Exception说是这个Exception 却也得到了和general rule 一样的境遇，然后给出的结论是：这个exception 肯定不在符合general rule 的那个category 里面的

楼主按照这个套路去读后面的选项，就只有A是符合这个套路的；
楼主再看看D, D 说到是exception 并没有得到和general rule 一样的待遇，所以是不对的

希望对楼主有帮助
