34.DS:如图，X，Y都生产80件以上，如果需要两人赚的银子相同，要多少件？

1）x-y=某个数，多少忘了 2）Y赚了126元

这题不应该理解X生产了a件 Y生产a+10件吗

这题选C对吗？

弱弱的问一下  50行的文章+4题 理论上多少时间应该完成？

3X for sharing

50行的话一般是平均一道题两分钟吧,我没具体看过,也就是总共8分钟完成差不多

verbal的速度sc一分钟一道,cr一分半到两分钟一道,rc两分钟一道

这样时间一般就比较充裕了

GWD12 Q29:

The Earth’s rivers constantly carry dissolved salts into its oceans.  Clearly,
therefore, by taking the resulting increase in salt levels in the
oceans over the past hundred years and then determining how many
centuries of such increases it would have taken the oceans to reach
current salt levels from a hypothetical initial salt-free state, the
maximum age of the Earth’s oceans can be accurately estimated.

 

Which of the following is an assumption on which the argument depends?

 

1. The
   quantities of dissolved salts deposited by rivers in the Earth’s oceans
   have not been unusually large during the past hundred years.
2. At any given time, all the Earth’s rivers have about the same salt levels.
3. There are salts that leach into the Earth’s oceans directly from the ocean floor.
4. There is no method superior to that based on salt levels for estimating the maximum age of the Earth’s oceans.
5. None of the salts carried into the Earth’s oceans by rivers are used up by biological activity in the oceans.

选a  lawyer 最后承认选a 了

给出三个数据，总人数３０，三项活动ＡＢＣ分别有１５，１７，２０参加，问最小的交集即三项活动都参加的人最少是多少。

答案
        为0，

其实上面的方法都太麻烦，在考试时容易搞晕头，下面给出最通用最简单最容易记的算法。
设N＝A+B+C－2T
如果N<=0,则A,B,C可以没有交集，
如果N>0,则A,B,C的交集最小为N。
