Math 4*,Verbal 2*, TTL 6**

考得不好, 但是我的目标只是国内的几个MBA项目, 因此马马虎虎可用而已. 在回家的路上,回忆起一些JJ,但是我的数学不到50,应该错了三题,数学总体难度不大.为了不误导大家了,所以以下只说题,不讲答案;语文更差,就更不误导各位了.但本着有聊胜于无
的原则,大家参考一下吧.

第一部分 JJ
AI No 2
AA No 12

Math:
先说几个我个人觉地有难度的题:
1.x is the range of set S, y is the range of set T, T belong to S, x>y?
(1) The numbers in S is 7
(2) The numbers in T is 6

2. there are some balls, 9 is blue and others is red. If select 2 from them,
the possibility of both blue is 6/11, the number of all balls?
题目不难,但是反过来问,以前没碰过.

3/4 3x-5y=?
(1) 1/0.5x - 1/0.3y = 1/4
(2) 1/0.3x - 1/0.5y = 3/8

2x-3y=?
(1) 1/0.3x - 1/0.2y = 1/4
(2) 1/0.2x - 1/0.3y = 3/8

现在想想,其实不难,但当时可能两道题我都做错了.

以下是白痴题, 只是小心点而已:

5. 1/(2+(1/(2+2)))=?

6. (123,456,789)^2 的个位数,百位数?

7. 6 different books, select 4, the combination?

8. 30% of 1/5=?

9. Is N the multiply of 36
1. 18 is a factor of N
2. 20 is a factor of N

10. Is M*N an even (M,N are integer)
1. M is even
2. N is even

11. 正方体的两条对角线的夹角的度数?

12. 等腰直角三角形的直角边是4,直角所对的边与另一等边三角形相接,求这四边形的面积.

13. x=-ky+k, 已知斜率是1/2, 求k? (数字可能不对)

14. $100,000, if the interests rate is x%, then the interest is $600,
if rate is y% and get interest $600, then the input is:
(1) Y=3
(2) Y=0.5x

15. 两水管灌水,A管单独用C小时,B管单独用T小时(C I: ?
II: 0 III: C/2 < S < T/2

16. the ratio of teachers and students is 1/12 last year, if increase 14 teachers and 74 students
this year, the ratio is 1/13. The number of students this year?

17. 图表题: 提供十个国家的人均用水量,以下正确的是:
I: 两个国家的人均用水量的倍数...
II: 后五个国家的中数...
III: 两个国家的人均用水量的平均数...
