Question 2
Problem Solving


A carpenter constructed a rectangular sandbox with a capacity of 10 cubic feet. If the carpenter were to make a similar sandbox twice as long, twice as wide and twice as high as the first sandbox, what would be the capacity, in cubic feet, of the second sandbox?

ANSWER

a) 20
b) 40
c) 60
d) 80
e) 100

Question 3
Critical reasoning

A company is considering changing its policy concerning daily working hours. Currently, this company requires all employees to arrive at work at 8am. The proposed policy would permit each employee to decide when to arrive – from as early as 6am to as late as 10am.

The adoption of this policy would be most likely to decrease employees’ productivity if the employees’ job functions required them to……

ANSWER

a) work without interruption from other employees
b) consult at least once a day with employees from other companies
c) submit their work for a supervisor’s eventual approval
d) interact with each other throughout the entire workday
e) undertake projects that take several days to complete

Question 4
Data Sufficiency – please determine whether the data provided by the statements are sufficient to answer the question.

In Jefferson School, 300 students study French or Spanish or both. If 100 of these students do not study French, how many of these students study both French and Spanish?

ANSWER

1) Of the 300 students, 60 do not study Spanish.
2) A total of 240 of the students study Spanish.

A. If statement (1) ALONE is sufficient to answer the question, but statement (2) alone is not;
B. If statement (2) ALONE is sufficient to answer the question, but statement (1) by itself is not;
C. BOTH statements (1) and (2) TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient;
D. EACH statement ALONE is sufficient to answer the question
E. Statement (1) and (2) TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

Q2:一个木匠做了一个长方形的沙盒(?),沙盒容量是10立方英尺。如果木匠要做第二个沙盒,这个沙盒的长、宽、高分别是第一个2倍。那么第二个沙盒的容量是多少?  
A2:这道题需要解释吗?假设第一个沙盒的长宽高分别为x,y,z,那么第二个的长宽高则为2x,2y,2z。已知xyz=10,问2x*2y*2z=?  实际上就是80

Q3:一个公司正在考虑更改其上班时间。目前,公司要求所有雇员在早上8点准时到达。而这次提交的方案将让每个雇员自己决定上班时间——早上6点到或者上午10点到。采用这种方案将最大程度降低员工的工作效率,如果雇员的工作需要...a)工作不被其他雇员打扰。b)至少一天一次咨询其他公司的雇员。c)提交他们的工作来获得上级的最终同意。d)每个工作日整整一天都和其他人互动。e)执行一个需要几天才能完成的任务。
A3:仔细想想,只有当工作需要其他员工协同完成时,其他人的缺席才能导致工作无法正常进行。d是最佳答案。

Q4:题目很简单,就直接跳过了。。。
A4:设同时学西班牙和法语的同学有x人,只学习西班牙的同学有y人,只学习法语的人有z人。x+y+z=300且y=100。求x
1)300人当中,60人不学西班牙语。(即z=60)  因此可以得出x=140
2)x+y=240。x=140

ANSWER

a) 20
b) 40
c) 60
d) 80
e) 100

x*y*z=10
(2x)*(2y)*(2z) = 8*xyz = 80

A company is considering changing its policy concerning daily working hours. Currently, this company requires all employees to arrive at work at 8am. The proposed policy would permit each employee to decide when to arrive – from as early as 6am to as late as 10am.

The adoption of this policy would be most likely to decrease employees’ productivity if the employees’ job functions required them to……

ANSWER

a) work without interruption from other employees
b) consult at least once a day with employees from other companies
c) submit their work for a supervisor’s eventual approval
d) interact with each other throughout the entire workday
e) undertake projects that take several days to complete

This is more like common sense. If D) is required, then those who arrive at 6 am might not have enough time to interact with those who arrive at 10 am. Hence the productivity of the company as a whole would decrease.

All the other choices would not link directly with the proposed policay change.

Question 4
Data Sufficiency – please determine whether the data provided by the statements are sufficient to answer the question.

In Jefferson School, 300 students study French or Spanish or both. If 100 of these students do not study French, how many of these students study both French and Spanish?

ANSWER

1) Of the 300 students, 60 do not study Spanish.
2) A total of 240 of the students study Spanish.

Only French: x
Only Spanish: y
Both: z
x+y+z=300
y=100
So, x+z=200
What is the value of z?

1) x=60. Then z= 140.  Sufficient
2) y+z=240. Then z=140. Sufficient

Choose D.
