一直在CD收益很多,虽成绩难于启齿,但还是希望贡献少量JJ给大家。今天AWA,Math (M:51,V:**)都还可以,只是最后Verbal乱了节奏,题目做到一半时时间已所剩不多,后面的一直在赶时间,题目都是粗粗看过,最后导致毁灭性的结果,每道题目都很重要,不管前后。希望大家引以为戒,不以物喜,不以物悲,保持平常心迎战。祝大家都考出好成绩! AA: "“Across town in the Park Hill district, the Thespian Theater, Pizzazz Pizza, and the Niblick Golf Club have all had business increases over the past two years. Capital Idea should therefore invest in the Roxy Playhouse, the Slice-o’-Pizza, and the Divot Golf Club, three new businesses in the Irongate district. As a condition, we should require them to participate in a special program: Any customer who patronizes two of the businesses will receive a substantial discount at the third. By motivating customers to patronize all three, we will thus contribute to the profitability of each and maximize our return.”"
AI: Fanicial gain palys an important factor in choosing a career. Math,有部分是JJ里面出现的,虽然题目似曾相识,但问法很多都换了形式,所以大家一定要细心谨慎:
1. confirmed: 还有一道是有一个五边形,所有的内角都是用x来表示的,加起来是10x,所以10x=内角和=540,x=54,求一个3x角的外交,就是180-3×54=18! 2. confirmed: 一个fraction,分子,分母也是integers,其中一个偶数,一个奇数,求分子是否偶数 (1)fraction > 1 (2)fraction 是整数,Key: B. 3. confirmed: 求过去13天卖书的median(1)过去7天每天卖43本 (2)过去13天卖了400本, 选A. 4. confirmed: 求6是否(m+1)(m-1)的factor(1)m is not divisble by 2 (2) m is not divisble by 3 ; Key: C. 5. confirmed: 一段路總共40mi. 某用60mi/hr 走了前30mi然後用30mi/hr 走了剩下的路, 問該女子最後平均的avg speed多少. Key is 48. 6. confirmed: a做3dozen每小时,b为4dozen每小时,每一刻至少有之一在做工,问至少两个一起同时做多少小时,能保证14小时完成77dozen,答案是第一个7h 7. 变形:(DS)S=a^2*b^3*c^n*d^5,how many factors in the product?? (1)a,b,c,d are prmie factors, some or all are same. (2) n = 4... Key: E. (very tricky) Analyse: (1) when a, b, c, d are different prime factors, S's factor is calculated and fixed, as some of them might be same, so it's uncertain for the final number of the factors. (2) only n = 4 is not sufficient to conclude the final factor as a,b,c,d are uncertain. So, both are insufficient. answer should be E. 8. Confirmed: 能否求出a、b、c、d四个数的标准差(1) a+b+c+d=某个数,… (2) a^2+b^2+c^2+d^2=另一个数, Key: C. 9. confirmed: 盐水浓度题。 10. confirmed: 问S是否大于T,其中S>0.(1)|s-t|=t(2)|s-t|=7; key: A 11. 已知:1,2,3,...25的和是325,, 求26...50inclusive的和: (Key: 950). 12. confirmed: 330是1乘到n 的乘积的因子,问n最小是多少,330=2x3x5x11, 选11 13. confirmed: 有一个2层停车场,全部停的车有30%是蓝色的,问停2楼的车不是蓝色的有几辆? (1)一楼停的有75辆车,20%是蓝的;(2)全部是蓝的有25辆; 选C 14. confirmed: 五个正整数p,q,r,s,t算术平均数是18,其中t=40,问median最大值; 22 15. confirmed: R 的排序方式: 给5个字母:ROEDR,记住,2个R!问2个R中间至少隔2个字母的排列方式有多少种,Key:18。 16. 我的最后一题: 一个厂子有两个department, one is X department, the other is Y , total profit is 1.4 million,X sale 和全部sales的比列等于X profit 和 all department 的profit 的比例,问X的profit 占总的profit的比列是多少 (1)Y sales is 20million(2)X与Y的sales的比例。选B Verbal: 没碰到SC,CR的JJ, 文章有 金星上的岩浆 bench marketing 的分类: 美国在国外的资本投资 measurement bias
