终于考完试啦,记忆中有几道数狗狗,不知道机经中有没有
1.有80个A, B的两个东西,A是每个2.5元(应该),B是每个3元(数字确定),然后A和B的均价是2.25(数学确定),问有多少个A。
选项有:15,20,25,30,35
2. 补充一到现有的JJ题,应该是变体,一个圆s, 内切于正方形A,外接圆正方形B,问圆S的周长是不是大于10.
(1)正方形B的边长大于2
(2)正方形A的边长大于2
3.画了个草图,意思就是ABCD是个四边形,AD长是X, DC长是X,角D是直角,角C是35, 角B是60,问四边形的周长。
选项有A。(2+根号2)x, B(2+2分之根号2)x,C (2+2根号6)X, D(2+根号6)X, E(2+二分之根号6)x (选项顺序不一定)
4.有一道机经中已经有的,但是我专门记了下数字,就是一个部门的奖金有三种,750,1500,和7500.每个奖金都要保证起码给一个人,然后总奖金是66,000,问最少给了几个人
选项有:10、11、12、13、14
5.一道PS题,已知n是整数,问X必是整数的选项
选项有:x+1=n, x+1/n=n, x方=n,然后有个想不起来了,反正无干扰,最后一个是根号x=n
先贡献几个数学,Verbal我再回忆回忆。。。
对了,再补充一道逻辑题,我搜了一下是prep的原题。
直接贴出来了,就是这道!但是选项顺序不同,原题正确答案是E,考试的时候,在A的位置 When feeding, aquatic birds known as phalaropesoften spin rapidly on the water’s surface, pecking for food during eachrevolution. To execute these spins,phalaropes kick one leg harder than the other. This action creates upwelling currents. Because plankton on which phalaropes feed typically occurs in greaterquantities well below the surface, it is hypothesized that by spinningphalaropes gain access to food that would otherwise be beyond their reach.
Which of the following, if true, most stronglysupports the hypothesis?
A. Phalaropes rarely feed while on land.
B. A given phalarope spins exclusively either tothe right or to the left.
C. Phalaropes sometimes spin when they are notfeeding.
D. Different phalaropes spin at somewhat differentrates.
E. Phalaropes do not usually spin when food isabundant at the surface.
