AWA: AA: 31. The following appeared as part of the business plan of an investment and financial consulting firm.
“Studies suggest that an average coffee drinker’s consumption of coffee increases with age, from age 10 through age 60. Even after age 60, coffee consumption remains high. The average cola drinker’s consumption of cola, however, declines with increasing age. Both of these trends have remained stable for the past 40 years. Given that the number of older adults will significantly increase as the population ages over the next 20 years, it follows that the demand for coffee will increase and the demand for cola will decrease during this period. We should, therefore, consider transferring our investments from Cola Loca to Early Bird Coffee.”
AI: 29. “Too many people think only about getting results. The key to success, however, is to focus on the specific task at hand and not to worry about results.”

数学碰到了不少JJ，但是很惭愧还是没有拿高分，而且没有办法像NN一样记得很多题（老实说，考试的时候我还在想要把题记下来发给大家，可是一考完就差不多都忘了-.-）印象中比较深刻的题是：
X 四舍五入后是否是3？
1) X^2四舍五入后是9 2) X^3四舍五入后是27 没有思路，算了半天，觉得B可能是对的，大概是错的，请大家讨论一下吧
投资者投资三个项目，每个项目独立，投资者能从至少一个项目中盈利的概率是多少？
1) 一个项目的盈利率是80% 2) 另两个项目的盈利率相等
我选E
(1+t)^2被4除的余数是多少？
1) t 被 2 整除
2) t 被 4 整除
我选B，余数为1
一个圆上三个点A,B,C, A和B是一条线段的两端，点O在AB上，问O是圆心吗？（怎么在帖子上画图呢？）
1) AO=BO 2) BO=DO 我选C
已知一辆车每mile耗28 gallons油（数字可能记错）问一辆车上个礼拜耗了多少油？
1) 上个礼拜一共开了N miles（数字不记得了）
2) 不好意思不记得了，不过这个条件好像不行
我选A
还有一题，以前的JJ里提到，67题，但当时算时一直没有算到给出的答案，今天看到原题，觉得可能是之前那位同学给的答案不对，不过也不确定，大家注意一下
67.mary has 2000 dollars half is saved in a simple interest rate, and the other half is saved in semi-annual compound interest rate of 8%. at the end of the year the interest earned from these savings accounts equal to each other. what is the simple interest rate.
1). 8.16
2). 8.23
3). 8.25
4). 8.45 今天碰到的和67题的数字和算法一样，只是表述上稍有差别（两个人分别以单利和复利存银行），答案里没有8.23，是8.32，我考前看JJ时算出来也是8.32，所以可能是记错了，请NN确认
暂时想到这些，晚点想到再补充，有好几道题是以前JJ上有的，所以不再发了。
