An 18 story office building has 15,000 square feet on each floor. Company “A” rents 9 floors and Company “B” rents 4 floors. What is the number of square feet of unrented floor space?
- A.
135,000
- B.
195,000
- C.
210,000
- D.
75,000
- E.
60,000
Correct Answer
D. 75,000Explanation
Company A rents 9 floors, which means they occupy a total of 9 * 15,000 = 135,000 square feet. Company B rents 4 floors, which means they occupy a total of 4 * 15,000 = 60,000 square feet. The total square footage occupied by both companies is 135,000 + 60,000 = 195,000 square feet. Since the building has a total of 18 floors, the remaining unrented floor space is 18 * 15,000 - 195,000 = 75,000 square feet. Therefore, the correct answer is 75,000.Rate this question:

If 16 file cabinets require 24 feet of wall space, 40 cabinets will require how many feet of wall space?
- A.
50
- B.
55
- C.
60
- D.

A secretary spends 1/4 of her time each week filing, 3/8 of her time typing, and the rest of the time entering data. During a normal 40 hour week, how many hours would be spent entering data?
- A.
15 Hours
- B.
10 Hours
- C.
5 Hours
- D.
20 Hours
- E.
25 Hours
Correct Answer
A. 15 HoursExplanation
The secretary spends 1/4 of her time filing and 3/8 of her time typing. To find the time spent entering data, we need to subtract the time spent filing and typing from the total time. Since 1/4 + 3/8 = 5/8, the secretary spends 5/8 of her time filing and typing. Therefore, the remaining time for entering data is 1 - 5/8 = 3/8. Since the total time is 40 hours, the time spent entering data is (3/8) * 40 = 15 hours.Rate this question:

An employee receives overtime at the rate of 1-1/2 times his regular rate for work over 40 hours performed on weekdays. For any time worked on Sundays or holidays he is paid double his usual rate. John Jones worked his regular 40 hours, and he also incurred 4 hours extra on Friday and 5 hours extra on Sunday, for a total of 49 hours for the week. His regular rate of pay is $15.00 per hour. What should his gross pay be for the week?
- A.
$730.50
- B.
$840.00
- C.
$810.00
- D.
$800.25
- E.
$600.00
Correct Answer
B. $840.00Explanation
John Jones worked 40 regular hours at a rate of $15.00 per hour, which amounts to $600.00. He worked 4 extra hours on Friday, which should be paid at 1-1/2 times his regular rate. So, 4 hours * $15.00 * 1.5 = $90.00. He also worked 5 extra hours on Sunday, which should be paid at double his regular rate. So, 5 hours * $15.00 * 2 = $150.00. Adding all the amounts together, his gross pay for the week should be $600.00 + $90.00 + $150.00 = $840.00.Rate this question:

The average salary of the three clerks is $450 per week. If one clerk earns $550, a second earns $300, how much is the salary of the third clerk?
- A.
$450
- B.
$850
- C.
$500
- D.
$750
- E.
$550
Correct Answer
C. $500Explanation
Based on the given information, the average salary of the three clerks is $450 per week. If one clerk earns $550 and a second clerk earns $300, we can calculate the total salary of the three clerks by multiplying the average salary by the number of clerks. Therefore, the total salary of the three clerks is $450 x 3 = $1350. To find the salary of the third clerk, we subtract the salaries of the first two clerks from the total salary. $1350 - $550 - $300 = $500. Therefore, the salary of the third clerk is $500.Rate this question:

If a gear makes 12 turns in 1/8 of a second, how many turns will it make in 20 seconds?
- A.
1920 turns
- B.
192 turns
- C.
30 turns
- D.
240 turns
- E.
96 turns
Correct Answer
A. 1920 turnsExplanation
The gear makes 12 turns in 1/8 of a second. To find out how many turns it will make in 20 seconds, we can set up a proportion. Since 1/8 of a second is equal to 12 turns, we can set up the proportion: (1/8) second = 12 turns and 20 seconds = x turns. Cross multiplying, we get 1 * x = (1/8) * 20 * 12. Simplifying this equation, we find that x = 1920 turns. Therefore, the gear will make 1920 turns in 20 seconds.Rate this question:

A storage shelf measures 2 feet by 3 feet by 5 feet. How many boxes 2 feet by 1 foot by 1 foot could be put on the shelf?
- A.
15 boxes
- B.
30 boxes
- C.
3 boxes
- D.
7 boxes
- E.
12 boxes
Correct Answer
A. 15 boxesExplanation
The storage shelf measures 2 feet by 3 feet by 5 feet, which means it has a volume of 2 x 3 x 5 = 30 cubic feet. Each box measures 2 feet by 1 foot by 1 foot, which means it has a volume of 2 x 1 x 1 = 2 cubic feet. To find out how many boxes can fit on the shelf, we divide the volume of the shelf by the volume of each box: 30 / 2 = 15. Therefore, 15 boxes can be put on the shelf.Rate this question:

At 5 a.m. the temperature was 62.5 degrees and at 8 a.m. the temperature was 67.0 degrees. Assuming a constant rate of increase, what time was it when the temperature was 65.5 degrees?
- A.
7:45 am
- B.
7:00 am
- C.
6:30 am
- D.
6:45 am
- E.
6:00 am
Correct Answer
B. 7:00 amExplanation
The temperature increased by 4.5 degrees in a span of 3 hours (from 5 a.m. to 8 a.m.). Therefore, the rate of increase is 4.5 degrees per 3 hours, which is equivalent to 1.5 degrees per hour. To find the time when the temperature was 65.5 degrees, we need to calculate how many hours it took for the temperature to increase by 3 degrees (67.0 - 65.5). Since the rate of increase is 1.5 degrees per hour, it took 2 hours (3 degrees / 1.5 degrees per hour). Adding this to the initial time of 5 a.m., we get 7 a.m. as the time when the temperature was 65.5 degrees.Rate this question:

A business with an income of $1,100,000 budgets 1/10 of its income to advertising. If the income of the company is budgeted to decrease by 20%, what would be the amount budgeted for advertising?
- A.
$22,000
- B.
$880,000
- C.
$220,000
- D.
$88,000
- E.
$110,000
Correct Answer
D. $88,000Explanation
The business budgets 1/10 of its income for advertising, which is equal to $1,100,000/10 = $110,000. If the income of the company is budgeted to decrease by 20%, the new income would be $1,100,000 - ($1,100,000 * 20%) = $1,100,000 - $220,000 = $880,000. Therefore, the amount budgeted for advertising would also decrease by 20% to 1/10 of the new income, which is equal to $880,000/10 = $88,000.Rate this question:

An IBM sorting machine operates at a rate of 450 cards per minute. 18,000 cards have to be put through the machine five times to complete a job. How long will it take to complete the job?
- A.
2 hours
- B.
3 hrs/30 min
- C.
3hrs/20 min
- D.
4 hours
- E.
3 hrs/33 min
Correct Answer
C. 3hrs/20 minExplanation
The sorting machine operates at a rate of 450 cards per minute. To complete the job, 18,000 cards have to be put through the machine five times. Therefore, the total number of cards to be processed is 18,000 * 5 = 90,000 cards.
If the machine can process 450 cards per minute, then it will take 90,000 cards / 450 cards per minute = 200 minutes to process all the cards.
Since there are 60 minutes in an hour, 200 minutes is equal to 200/60 = 3 hours and 20 minutes. Therefore, it will take 3 hours and 20 minutes to complete the job.Rate this question:

A certain factory employs 2000 women, 1,500 single men, and 6,500 married men. If each group is expanded proportionally until there are 11,500 employees, what will the number of the additional women be?
- A.
150
- B.
230
- C.
300
- D.
500
- E.
975
Correct Answer
C. 300Explanation
The total number of employees in the factory is 2000 + 1500 + 6500 = 10000. To find the proportion of women in the total number of employees, we divide the number of women by the total number of employees: 2000 / 10000 = 0.2.
If we expand the total number of employees to 11500, we can find the number of additional women by multiplying the expanded total by the proportion of women: 11500 * 0.2 = 2300.
Therefore, the number of additional women will be 2300 - 2000 = 300.Rate this question:

A machine operates at the rate of 650 operations per minute; however, 20% must be deducted to allow for machine handling time by the operator. There are 13,000 operations to be put through the machine six times to complete the job. How long will it take?
- A.
1 hr/20 min
- B.
2 hrs/50 min
- C.
2 hrs/30 min
- D.
3 hrs/2 min
- E.
2 hours
Correct Answer
C. 2 hrs/30 minExplanation
The machine operates at a rate of 650 operations per minute, but 20% must be deducted for machine handling time. This means that the machine can actually process 80% of the operations per minute. To find out how long it will take to complete the job, we need to calculate the total number of operations and divide it by the number of operations the machine can process per minute.
The total number of operations is 13,000 multiplied by 6 (since the job needs to be completed six times). This equals 78,000 operations.
To find out how long it will take, we divide 78,000 by 650 operations per minute (80% of the machine's rate).
78,000 / (650 * 0.8) = 2 hours and 30 minutes.
Therefore, the correct answer is 2 hrs/30 min.Rate this question:

A rectangular computer is 42 inches longer than it is wide and has a perimeter of 204 inches. What is the width of the machine?
- A.
30 inches
- B.
9 inches
- C.
72 inches
- D.
45 inches
- E.
40 inches
Correct Answer
A. 30 inchesExplanation
The rectangular computer is 42 inches longer than it is wide. Let's assume the width of the machine is x inches. Therefore, the length of the machine would be x + 42 inches. The perimeter of a rectangle is calculated by adding all four sides together, so we can set up the equation: 2(x + x + 42) = 204. Simplifying this equation, we get 4x + 84 = 204. By solving for x, we find that the width of the machine is 30 inches.Rate this question:
