标题: 9.27 放狗
数学遇到了好几道机经的题，另外印象深刻一点的：
1.有一个right clinder给了直径和高，说有16个这个填充进一个rectangular里面，也给了长宽高，用S代表这个填充比例，另外还有sphere好像是（或者是其他形状），也是填充进这个rectangular里面，比例为C，这三种形状都给了体积公式不用记，然后问你S和C的关系。就是带入公式然后算出来就行，我记得是C比S多50%还是S比C多50%，计算还好主要是我看题看了很久。
2.一家公司在snack、store和restaurant的profit占比给了，然后问你这三个profit的和，就是分数转换，我做到这道题是最后一题，以为完蛋了掉裤也太夸张了啊。。。但是最后虽然没有51有50，所以不要轻易判断。
3.有一个集合有abcde元素，问你在他的32个子集里面恰好有3个元素的集合有多少种。就是C53.
4.又想起来一个，补充前面的寂静。f(x)=n*n!（或是别的，我也忘了。。），问你f(n+1)-f(n)，这个带入后我好像是算出来是（n+1)*(n+1)!.我现在怎么算不出来了。。。
实在也想不起来别的了。
阅读：考了一个bundling销售的，还有一个说一个海里的生物会释放一种有毒的物质然后导致吃他的其他生物就如何变化的balabala，我觉的这篇不难，也导致我verbal死的很惨，另外有什么大牛可以传授一些verbal的复习方法实在感激不尽。特别是阅读。
逻辑的话我也真的想不起来什么了。。。祝大家考试成功。我继续寻找复习V的方法了。

又想起来一个，说rn+1-rn=（-1)^n/2^n,问r1、r2、r3的大小关系。带入进去就能知道，最后是r2<r3<r1

不是，第二段也有说一个实验，然后有一道高亮题说实验里面选择的这个natural的捕食者是什么意思。

请问楼主还记得作文吗？

作文是说一个公司的manager说in the past month，gasoline prices有一个上升，然后同时消费者买大车的少了，所以这个公司就说要把production转换为生产小车，fuel-efficient的车，说这样可以maintain sales，大概是这样

请问构筑，捆绑销售的是一个是aggregation bundling，另一个是loyalty bundling吗？谢谢！

感谢楼主！再请楼主高抬贵眼看看这个考古是不是原文！
Aggregation Bundling：
This concept involves producing a bundle that will appeal to a number of customer segments. Suppose you have four items: A, B, C, and D. One segment strongly prefers the first three, and a second segment strongly prefers the last three. It may be possible to combine all four items into one bundle and price it so that both segments will purchase it, albeit for different reasons. That is, by bundling, you are combining segments of the market with different tastes and preferences into an aggregate segment with a similar valuation for the bundle. The goal is to attract a large market and reduce complexity by having fewer products. The secret is in pricing the bundle so that your comprehensive offering is more attractive than specialized bundles offered by competitors. A corollary of the basic strategy is to produce, in addition, special bundles (or individual items) for smaller market segments at higher prices.

Credit card firms use this strategy. The typical credit card includes a wide variety of services. It is unlikely that a large segment of subscribers actually are interested in all of these services. Customers who travel frequently may value car rental insurance or access to traveler's checks in foreign countries. Others may value a purchase protection plan. They all buy the same card.

Loyalty Bundling：

Here the basic idea is to expand sales by reducing customer incentives to sample and perhaps switch to a competitor's product. CitiCorp has used its CitiOne financial account successfully to this effect. Customers who purchase this account receive a reduced price on a bundle of services. For example, a minimum balance in a money market account gives the customer check writing privileges at no charge. CitiCorp also wins. First, it gains operating efficiencies. It costs about the same amount to open one or several accounts for a customer at the same time. A bundled account opens several accounts simultaneously. Second, Citicorp's research shows that customers who purchase two or more products from the same institution are unusually loyal. Once the accounts are open, the transaction cost to the customer is very low. A person is more apt to move funds from the checking account to the money market fund during a cash transaction than to initiate a new transaction with a competing bank. Thus for no increase in its operating cost, CitiCorp obtains a sales advantage.

Consumer goods firms also package products in order to build manufacturer loyalty, or at least to encourage switching only among their own offerings. Cereal manufacturers offer different "variety packs" geared to adults and children. Each pack has between six and twelve different brands of cereals. Firms satisfy consumer desire for variety while retaining their customers under the broad umbrella of one manufacturer.

他有做修改，把这两种合并在一起，先介绍了bundling的方法，然后分别介绍的，内容是差不多的但是没有解释的这么详细
