q50，v不太好，pace不好，后面来不及做了。。放狗攒rp

输血829的库可以多看看，有好几道中的
说几道记得的新的
1.一个公司新来了一批人之后，公司的平均薪资增加了5，问的好像是新来的占原来人数的比例，ds题，但是条件都想不起来了，但是很抽象，没有什么具体的数据

2.  （10^10*9 ）- （10^5*2）问最接近哪个值
我选的10^11

3.有四个人，排成一行，要求第一个和最后一个的性别相同。问有多少种排列可能。ds题。
  条件1: 4人中至少有一个男的
  条件2: 女性人数多于男性人数

4.有一个n位数，交换其中任意两个数位的数字，得到的新的n位数被称为是原来那个n位数的trans什么数。然后现在有一个493572？？具体不记得原树是什么了？然后问交换两个数位后，后两位数位之和是4的倍数，问满足这个要求的trans数有几个（好像是）

其他不记得了，应用题和数论题比较多，有难度

月度：
中了冥王星和yellow paper

还有一篇好像讲的是国际公司globalization还是standardization，讲到什么multiculture的，最后一篇所以来不及细看了

还有一篇：在没有科技机器的时候，地球资源可以承担的人口只有1billion，后来因为因为机器/和技术进步，对资源利用更有效了，地球资源能承担的人口数量就变多了。还有一个原因是农业技术的进步，通过不贵的化石燃料，新的大规模灌溉技术什么的实现的。然后说如果以后化石燃料资源变贵了（有题），农业会受影响。

坐稳：
一个汽车公司的经理说，6月他们集中宣传luxury汽车的时候，luxury汽车和普通汽车的sales都提高了，而2月份公司主要宣传不贵的普通汽车的时候，overall sales都是下降的。所以经理就说了，为了profit最大化，我们要全年都重点宣传luxury汽车。而且那些会被luxury汽车宣传吸引的顾客，买了luxury汽车后还会再买其他不同的车？

是原文吗？

Newspapers and magazines were sold on bookstalls, and publishers were not slow to see the opening for the sale of cheap, attractive, easy-to-carry, paperbound books. A whole series of ‘libraries’ of such books was developed, initially to appeal to first-class passengers—the first volume in Murray’s Library of Railway Readings consisted of selected articles from The Times. The range soon widened and by the later 1850s the yellow backs’, so called because they were characteristically bound in glazed yellow paper, crowded the bookstalls. Some series were reprints of older works and some were original, so-called ‘railway’ novels. In addition to fiction, there were non-fiction works and topical books on, for example, the Crimean War and the Indian Mutiny. Most of the books sold for one or two shillings and, although they were more expensive than newspapers, they provided more reading matter. The bright display of books in the mundane background of the station, the ease and cheapness of buying them, and the lack of pretension in their binding made them familiar objects and helped remove the mystique which had always surrounded books in the past. Books ceased to be altarpieces in temples of prosperity and became the everyday possessions of the common man.

不是，讲的是一个杂志，大意就是原作者写了yellow paper之后，有其他编辑在这个基础上修改什么的，也就是最后刊登出来的可能和原来原作者版本不同。是这一篇，jj里好像有
