151 A toy store regularly sells all stock at a discount of 20 percent to 40 percent .If an additional 25 percent were deducted from the discount price during a special sale, what sould be the lowest possible price of a toy costing $16 before any discount?
这个题目最后的before 是不是应该是after才对呢？不然 题目好像意思不太对呀。。。？
a toy costing $16 before any discount是一个整体来的，翻译过来就是：未打折前价格是$16的玩具。（这里的before any discount就近修饰，而不是跳跃修饰前面的price）
然后是DS题。我比较不擅长这个，所以题目会多一点，谢谢呀
86 A number of people each wrote down one of the first 30 positive integers. Were any of the integers written down by more than one of the people?
这个题目也没太看懂，它的逻辑，希望NN解释一下，谢谢~~
翻译过来的意思是：这里有一些人，他们中的每个人写下从1到30中的任何一个正整数。问，在被写下的数字中，是否至少有一个数被写下的次数超过2次。
这样翻译后问题应该就迎刃而解啦
98 seven different numbers are selected from the integers 1 to 100,and eache number is divided by 7 ,what is the sum of the remainders?
OG的解释很诡异的把这七个数字列为6 7 14 21 28 35.。。。。后面的解释我就没看，光是前面这个数字的假设我就没有想明白？？
这里面含了2步，第一步是从1到100里选7个数字，第二步是把这些书分别除以7，问你除了7以后这些数的余数的和是多少？
128 A school administrator will assign each student in a group of n students to one of m classrooms.If 3<m<13<n，is it possible to assigh each of the n students to one of the m classrooms so that eache classroom has the same number of students assigned to it ?
这题的意思是说：把学生分成若干小组，每个小组有7人，然后将每个小组分到m个班级里，问，是否有可能将这些小组分完后，每个班分到的学生一样多？
129 What is the median number of employees assigned per projuect for the projuects at Company Z?
这题其实是问：将每个项目的雇员人数进行排序，然后找出中值。
（1）和（2）分别告诉了超过或等于4人的项目占25%,少于或等于2人的项目占35%。由此可知，余下的40%应该是3人的项目，已排序，就能得出中值是3了。

50 How many people are directors of both Company K and Company R?
1）There were 17 directors present at a joint meeting of the directors of Company K and R,and no directors were absent.
2) Company K has 12 directiors and Company R has 8 directors.
这个题目的逻辑没看明白？
问题：Company K 和 Company R共有的董事共有多少个？
2个条件合在一块的意思就是：K有12个董事，R有8名董事。2家公司的所有董事都出席了一个会议，总人数是17人。12+8=20人，说明有20-17=3人是两家共有的董事。
以上是我整理的回复，希望能有所帮助。 |
