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.

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.作者: queenie924 时间: 2011-2-13 21:27
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.
