九月十一日機經(香港下午)

greenhorn1

今天很幸運,成績居然過700, 之前還擔心因為時間不夠,Verbal最後四條只是草草選了,會對分數有影響

AWA
Argument:
一個地方Retail price increases, 導致owner 算另一個地方買retail space.
Issue:
To become successful professionally, someone has to sacrifice personal life.

Quantitative:
和之前9月9 日的機經有點相似:
有大人和小孩一起看戲(共50人),花了一些錢買票和零食,問那一個condition is sufficient to find out number of adults.
另一條在gwd出現過: A circle with a centre on positive x-axis, 問哪一個condition is sufficient to find the radius: (1) x co-ordinate 是某數 (2) y co-ordinate 是某數
還有Find a median of n consecutive even integers (1) Median is a ratio of the remaining sum of integers (2) the sum of remaining integers excluding median is a figure
較難的是a circle centred on (3, -4) cuts x-axis on two points and the distance between the two points is 8. Find the circumference of the circle.

Verbal:
RC有法國女裁縫, 中耳構造, marketing strategy (bundle sales), 還有一個忘記了.
因為不夠時間,所越做心跳越快, 有很多一時忘了,如果記起會再補.

A circle with a centre on positive x-axis, 問哪一個condition is sufficient to find the radius:

(1) x co-ordinate 是某數
            

 

(2) y co-ordinate 是某數

 

Find a median of n consecutive even integers

 

 (1) Median is a ratio of the remaining sum of integers

 

(2) the sum of remaining integers excluding median is a figure

 

明天要考试了，想请教这两题
            思路，完全没头绪阿

第一條答案應該是a,因為圓上的一點可以是2nd or 3rd quadrant. 其實是gwd的題,不過忘了那一條
第二條答案應該是d, 該題有給average of all numbers

(2) y co-ordinate 是某數

画图看的话，b吧

另一个看不懂，呼唤nn

两次他

没思路。。。

Let me explain the question related to circle.
There is a circle with centre P(3, 0) (I forgot the exact value). There is a point Q on the circle. What is the radius?
(1) The x co-ordinate of Q is -4 (I forget the exact value, but the sign is -ve)
(2) The y co-ordinate of Q is -4 (I forget the exact value, but the sign is -ve)

x co-ordinate 这个中文翻译时什么意思，突然大脑短路，是 X坐标吧

葫芦娃哈哈

還有Find a median of n consecutive even integers (1) Median is a ratio of the remaining sum of integers (2) the sum of remaining integers excluding median is a figure

 

 

第二條答案應該是d, 該題有給average of all numbers

问楼主：如果给了平均数，是不是知道n就可以知道median了？

所以条件1和条件2都是正确的。

是么？

感谢~
