[原创]8月4，新加坡 750 复习心得加一点数学JJ

Math:　51, Verbal: 40

潜水40天，终于可以做一点点贡献了

复习计划

完全借鉴 携隐GMAT小教室 第三期 （http://www.chasedream.com/show.aspx?id=2072&cid=39）， 同时读一些N人心得， 根据个人基础做一些取舍。

数学：考前我很担心， 因为平时总是粗心， 这次发挥不错， 总之是仔细，仔细，再仔细。

语文：考试中和平常作ＧＷＤ的感觉不一样，　觉得难度普遍加大，　特别是阅读，　我的感觉是ＧＭＡＴ实战（包括ＧＭＡＴＰｒｅｐａｒｅ）的文章难度比ＧＷＤ大很多，而且出的题刁钻很多，　不知道大家有没有这种感觉。或许我做ＧＷＤ不够，因为时间关系我只做了ＧＷＤ１－１０．平时做题时间听充裕，考试时时间很紧，最后几道题没看仔细，结果还只剩下十几秒，　建议平时加快速度

ＧＭＡＴＰｒｅｐａｒｅ：虽然重题很多，效果还是不错，　考前模拟７５０，７６０，７７０

不多说了，一点数学ＪＪ：

1. (with figure)
squreroot(3) + squreroot(2)
--------------------------- = ?
squreroot(3) - squreroot(2)

(anw) there is a point in between 9 and 11

2. for savings into bank, for first 0 - 20,000, interest rate is 2 %, next 20,000

 to 50,000 interest rate is 2.5%,

 and above 50,000 interest is 3.5%, what is the saving amount that the interest equal to 3%?
(anw) 120,000

3. there are two set each with the number 1, 2, 3, 4 ,5, 6. ask randomly choose one number from each set, what is

the probability that the products of the 2 number is divisable by 4

(anw) 12/25, Note: dont forget 4*1, 4*3, 4*5, same I am wrong with this one, the anwer should be (9+6)/36, or my memory is wrong? wait for others to verify the question and anwer

4. DS: ab> ?
1) a-b >0
2) a+b <0

(anw) E,

5. DS: there is a set of number, the mean is m, the standard deviation is R, if add a number x to this set, if r

<= R?
1) x=m
2) m<x<m+R

(anw) D, Note: not sure about 2), made a guess here
6. DS: r, s, t has the same remainder when divided by 5, what is t?
1) r+s=t?
2) 20 <= t <=24

(anw) B, t=20

7. X, Y, Z are points on a line, Y is between X and Z, W is another ponit that WX=WZ, which of the folloing must

be true

(anw) there is many choices, i choose that WX>WY

8. what is the units number of
32,941 * (10^12 - 10^11)/10^13

(anw) the first number (32,941) may not be correct, but the question is similar

9. DS: there is a car and a trunck, in the same duration, car traveled 120 miles, and trunk travelled 100 miles.

what is the average speed of trunk in this period

1) in the first 30 min, car travelled 30 miles
2) the average speed of the car is 10 miles/hour more than the trunk

(anw) B

挥着猪翅膀

谢谢~~~

6. DS: r, s, t has the same remainder when divided by 5, what is t?
1) r+s=t?
2) 20 <= t <=24

(anw) B??---Ain't it C?

3. there are two set each with the number 1, 2, 3, 4 ,5, 6. ask randomly choose one number from each set, what is

the probability that the products of the 2 number is divisable by 4

(anw) 13/25???-----ain't it 13/36?

8. what is the units number of
32,941 * (10^12 - 10^11)/10^13

(anw) the first number (32,941) may not be correct, but the question is similar
is the unit number same to the unit number of 9*32941/100?

大家来DISCUSS一下啊~~

lovetiky

thank you for sharing!!

caterpillarcn

还有，恭喜LZ。

和LZ在一个地方，希望沾点喜气~~

baggiojia

我也是!沾沾!

5楼的GG你什么时候考?

分给偶一点

 

偶的杯子是用来接大小福神的，嘻嘻

(anw) B??---Ain't it C?这题什么思路?

3. there are two set each with the number 1, 2, 3, 4 ,5, 6. ask randomly choose one number from each set, what is

the probability that the products of the 2 number is divisable by 4

(anw) 13/25???-----ain't it 13/36? 不可以抽相同的嘛?比如2乘以2, 4乘以4. 我怎么是7/18?

8. what is the units number of
32,941 * (10^12 - 10^11)/10^13

(anw) the first number (32,941) may not be correct, but the question is similar
is the unit number same to the unit number of 9*32941/100?

是吧

顺便问下,第四题的r是哪来的? 是敲错了嘛? 应该是什么?

大家来DISCUSS一下啊~~

嗯，made a mistake in answer of 3, should be 13/36

for 6, 2) alone can identify t=20 as from the question can find that r, s, t all be divisable for 5

for 8, yes, u are right
