### N is an integer and n2 is divisible by 28. Which of the following must be true? I. n2 is divisible by 49. II. n is divisible by 4. III. n2/28 is divisible by 7.

• A.

I only

• B.

II only

• C.

I and III only

• D.

II and III only

• E.

I, II, and III

C. I and III only
Explanation
If n^2 is divisible by 28, it means that n^2 is a multiple of 28. Since 28 can be factored into 2^2 * 7, this means that n^2 must be divisible by both 2^2 and 7. Therefore, I is true.

For III to be true, n^2/28 must be divisible by 7. Since n^2 is already divisible by 28, dividing it by 28 means that it must also be divisible by 7. Therefore, III is also true.

However, there is no information given about whether n is divisible by 4, so II cannot be determined and is not necessarily true. Therefore, the correct answer is I and III only.

### If there are 85 students in a statistics class and we assume that there are 365 days in a year, what is the probability that at least two students in the class have the same birthday (assuming birthdays are distributed independently)?

D.
Explanation
The probability that at least two students in a class of 85 have the same birthday can be calculated using the concept of complementary probability. We first calculate the probability that no two students have the same birthday. The first student can have any birthday, while the second student must have a different birthday, which can be any of the remaining 364 days. Similarly, the third student can have a birthday on any of the remaining 363 days, and so on. Therefore, the probability that no two students have the same birthday is (365/365) * (364/365) * (363/365) * ... * (282/365). To find the probability that at least two students have the same birthday, we subtract this probability from 1.

### A test maker is to design a probability test from a list of 21 questions. The 21 questions are classified into three categories: hard, intermediate, and easy. If there are 7 questions in each category and the test maker is to select two questions from each category, how many different combinations of questions can the test maker put on the test?

• A.

(7!/(5!2!))3

• B.

(7!/(5!))3

• C.

(7!/(2!))3

• D.

3*29

• E.

72

A. (7!/(5!2!))3
Explanation
The test maker needs to select 2 questions from each category, so for each category, there are 7 choose 2 combinations. Since there are 3 categories, the total number of combinations is (7 choose 2) * (7 choose 2) * (7 choose 2) = (7!/(5!2!))3.

### There are five empty chairs in a row. If six men and four women are waiting to be seated, what is the probability that the seats will be occupied by two men and three women?

• A.

4/21

• B.

5/21

• C.

8/21

• D.

9/21

• E.

11/21

B. 5/21
Explanation
The probability of the seats being occupied by two men and three women can be calculated by dividing the number of favorable outcomes (arrangements with two men and three women) by the total number of possible outcomes. Since there are 6 men and 4 women waiting to be seated, the total number of possible outcomes is the number of ways to choose 2 men out of 6 multiplied by the number of ways to choose 3 women out of 4. This can be calculated as (6 choose 2) * (4 choose 3) = 15. Therefore, the probability is 15/210, which simplifies to 5/21.

### Mariah has decided to hire three workers. To determine whom she will hire, she has selected a group of 10 candidates. She plans to have one working interview with 3 of the 10 candidates every day to see how well they work together. How many days will it take her to have working interviews with all the different combinations of job candidates?

• A.

720

• B.

120

• C.

300

• D.

30

• E.

333

B. 120
Explanation
Mariah has selected a group of 10 candidates and plans to have one working interview with 3 candidates every day. To find out how many days it will take for her to have working interviews with all the different combinations of candidates, we need to calculate the number of combinations. The formula to calculate the number of combinations is nCr = n! / (r!(n-r)!), where n is the total number of candidates and r is the number of candidates selected for each interview. In this case, n = 10 and r = 3. Plugging these values into the formula, we get 10! / (3!(10-3)!), which simplifies to 10! / (3!7!). This further simplifies to (10*9*8) / (3*2*1), which equals 120. Therefore, it will take Mariah 120 days to have working interviews with all the different combinations of job candidates.

### A coin has two sides. One side has the number 1 on it and the other side has the number 2 on it. If the coin is flipped three times what is the probability that the sum of the numbers on the landing side of the coin will be greater than 4?

• A.

3/8

• B.

1/16

• C.

1/8

• D.

1/2

• E.

1/4

D. 1/2
Explanation
When a coin is flipped, there are two possible outcomes: either the number 1 or the number 2 will be on the landing side. Since the coin is flipped three times, there are a total of 2^3 = 8 possible outcomes. Out of these 8 outcomes, there are 4 outcomes where the sum of the numbers on the landing side is greater than 4: 2+2+2, 2+2+1, 2+1+2, and 1+2+2. Therefore, the probability of getting a sum greater than 4 is 4/8 = 1/2.

### Computer Games Plus needs to get rid of its copies of an old computer game. If it lowers the cost of the old computer game by \$5 dollars, it can increase sales of the old computer game by 10 units and still generate exactly \$100 of revenue from the old game. How many units of the old computer game did Computer Games Plus sell after implementing the new selling strategy?

• A.

10

• B.

15

• C.

20

• D.

30

• E.

50

C. 20
Explanation
By lowering the cost of the old computer game by \$5, Computer Games Plus can increase sales by 10 units and still generate \$100 of revenue. This means that each unit of the old computer game originally sold for \$10 (\$100 revenue divided by the original number of units sold). By lowering the cost by \$5, the new selling price is \$5. Therefore, the number of units sold after implementing the new strategy is 20 units (\$100 revenue divided by the new selling price of \$5 per unit).

### At a local appliance manufacturing facility, the workers received a 20% hourly pay raise due to extraordinary performance. If one worker decided to reduce the number of hours that he worked so that his overall pay would remain unchanged, by approximately what percent would he reduce the number of hours that he worked?

• A.

83%

• B.

80%

• C.

20%

• D.

17%

• E.

12%

D. 17%
Explanation
If the worker received a 20% hourly pay raise, it means that his hourly wage increased by 20%. In order for his overall pay to remain unchanged, he would need to reduce the number of hours he worked by a percentage that offsets the hourly pay raise. To find this percentage, we can set up the equation: (1 - x) * (1 + 0.20) = 1, where x is the percentage reduction in hours worked. Solving for x gives us x â‰ˆ 0.17, which is approximately 17%. Therefore, the worker would need to reduce the number of hours he worked by approximately 17% to maintain his overall pay unchanged.

### There are six different models that are to appear in a fashion show. Two are from Europe, two are from Africa, and two are from North America. If all the models from the same continent are to stand next to each other, how many ways can the fashion show organizer arrange the models?

• A.

48

• B.

64

• C.

24

• D.

8

• E.

72

A. 48
Explanation
The fashion show organizer can arrange the models in 48 different ways. To determine this, we can consider the models from each continent as a group. There are 3 groups of models (Europe, Africa, and North America) and within each group, there are 2 models. Therefore, we can arrange the groups in 3! = 6 ways. Within each group, we can arrange the models in 2! = 2 ways. Multiplying these together, we get 6 * 2 * 2 * 2 = 48.

### At a technology consulting firm with x computers, all of which are desktops or laptops, 30% are laptops; if 80% of the total number of computers have more than 1GB of RAM and 10% of the computers with less than 1GB of RAM are laptops (and no computers have exactly 1GM of RAM), approximately what percent of the desktops have more than 1GB of RAM?

• A.

75%

• B.

60%

• C.

52%

• D.

40%

• E.

45%

A. 75%
Explanation
Approximately 30% of the computers are laptops, which means that 70% are desktops. Since 80% of the total number of computers have more than 1GB of RAM, we can assume that the same percentage applies to both laptops and desktops. Therefore, approximately 80% of the desktops also have more than 1GB of RAM. This corresponds to the answer choice of 75%.

### A group of 5 investment bankers and 5 clients recently frequented the Fine Tiger Nigerian Restaurant. The total bill for the meal, including 20% gratuity, came to N960. On average, how much did the meal of each individual cost before gratuity?

• A.

N160

• B.

N96

• C.

N90

• D.

N80

• E.

N55

D. N80
Explanation
The total bill for the meal, including 20% gratuity, came to N960. To find the cost of each individual's meal before gratuity, we need to divide the total bill by the number of individuals. In this case, there are 5 investment bankers and 5 clients, so a total of 10 individuals. Dividing N960 by 10 gives us N96. However, the question asks for the average cost, so we need to divide N96 by 2 (the number of groups: investment bankers and clients). N96 divided by 2 equals N48, which is the cost of each individual's meal before gratuity.

### In a local intramural basketball league, there are 10 teams and each team plays every other team exactly one time. Assuming that each game is played by only two teams, how many games are played in total?

• A.

100

• B.

90

• C.

50

• D.

45

• E.

10

D. 45
Explanation
In a local intramural basketball league with 10 teams, each team plays every other team exactly once. To determine the total number of games played, we can use the combination formula. Since each game involves two teams, we need to find the number of combinations of 2 teams from a set of 10. The formula for this is nC2 = n! / (2!(n-2)!), where n is the number of teams. Plugging in the values, we get 10C2 = 10! / (2!(10-2)!) = 45. Therefore, a total of 45 games are played in the league.

### A box contains either blue or red flags. The total number of flags in the box is an even number. A group of children are asked to pick up two flags each. If all the flags are used up in the process such that 60% of the children have blue flags, and 55% have red flags, what percentage of children have flags of both the colors?

• A.

5%

• B.

10%

• C.

15%

• D.

20%

• E.

It cannot be determined

C. 15%
Explanation
Since 60% of the children have blue flags and 55% have red flags, it means that 60% + 55% = 115% of the children have either blue or red flags. However, since some children may have both blue and red flags, the total percentage of children with both colors cannot exceed 100%. Therefore, the maximum percentage of children with flags of both colors is 100% - 115% = 15%.

### There are 4 more women than there are men on a local co-ed softball team. If there are a total of 16 players on the team, what is the ratio of men to women?

• A.

10/16

• B.

6/16

• C.

4/16

• D.

6/10

• E.

4/10

D. 6/10
Explanation
Since there are 4 more women than men on the team, we can deduce that there are 6 women and 2 men. Therefore, the ratio of men to women is 2/6, which simplifies to 1/3. However, the answer choices do not include 1/3. The closest ratio is 4/10, which simplifies to 2/5. Therefore, the correct answer is 4/10.

### A computer has three hard-drives; the smallest and largest hard-drives account for 25 and 45 percent of the total storage space on the computer, respectively; due to a catastrophic error, the largest hard-drive lost approximately 22% of its storage space; after this error, the hard drive that was originally the second largest accounts for approximately what percent of the total hard-drive space on the reduced computer?

• A.

22%

• B.

33%

• C.

20%

• D.

39%

• E.

45%

B. 33%
Explanation
After the catastrophic error, the largest hard-drive lost approximately 22% of its storage space. Therefore, the remaining storage space on the largest hard-drive is 100% - 22% = 78%. Since the smallest hard-drive accounts for 25% of the total storage space, and the largest hard-drive now accounts for 78% of the reduced storage space, the second largest hard-drive must account for the remaining percentage. Thus, the hard drive that was originally the second largest accounts for approximately 100% - 25% - 78% = 33% of the total hard-drive space on the reduced computer.

• C.

N750,000

• D.

N27,000

• E.

N10,000

D. N27,000
Explanation
The question asks about the average daily sales prior to the advertising campaign. To find this, we need to divide the monthly sales (N1 million) by the number of days in a month. Assuming there are 30 days in a month, the average daily sales would be N1 million divided by 30, which equals N33,333. Therefore, the closest option to this is N27,000.

### Walking across campus, a student interviewed a group of students. 25% of the students took a finance class last semester, 50% took a marketing class last semester, and 40% took neither a finance nor a marketing class last semester. What percent of the students in the group took both a finance and a marketing class?

• A.

60%

• B.

50%

• C.

25%

• D.

15%

• E.

10%

D. 15%
Explanation
The correct answer is 15%. This can be determined by subtracting the percentage of students who took neither a finance nor a marketing class (40%) from the total percentage of students who took either a finance or a marketing class (100% - 40% = 60%). Since the total percentage of students who took both a finance and a marketing class cannot exceed the total percentage of students who took either class, the maximum percentage of students who took both classes is equal to the percentage of students who took either class (60%). Therefore, the percent of students in the group who took both a finance and a marketing class is 15% (60% - 45% = 15%).

• A.

75%

• B.

60%

• C.

52%

• D.

A. 75%
Explanation
Approximately 30% of the computers are laptops, which means that 70% are desktops. Out of the total number of computers, 80% have more than 1GB of RAM. Since no computers have exactly 1GB of RAM, all the computers with less than 1GB of RAM are desktops. We know that 10% of the computers with less than 1GB of RAM are laptops, so the remaining 90% must be desktops. Therefore, approximately 90% of the desktops have more than 1GB of RAM.

### Correct the part of the sentence underlined. Choose from the given options. During the summer of 2008, an unemployed investment banker with over 25 years of experience named Joshua Persky made news by walking the streets of New York City's financial district in a suit with a sandwich board advertising his services. Many social commentators disagreed on the implications of this, either seeing Joshua's efforts as a desperate and unprofessional manner to seek a job or they viewed Joshua's strategy as a savvy means to attract attention to an overly qualified individual.

• A.

Either seeing Joshua's efforts as a desperate and unprofessional manner to seek a job or they viewed Joshua's strategy as a savvy means to attract attention to an overly qualified individual.

• B.

Either seeing Joshua's efforts as a desperate and unprofessional manner to seek a job or viewing Joshua's strategy as a savvy means to attract attention to an overly qualified individual.

• C.

Seeing either Joshua's efforts as a desperate and unprofessional manner to seek a job or viewing Joshua's strategy as a savvy means to attract attention to an overly qualified individual.

• D.

### Samuel is obviously a bad fisherman. During the past season, in which he and the five members of his team spent four months on a boat together off Dutch Harbor, AK, he caught fewer fish than any of his teammates. Which of the following, if true, most weakens the argument above?

• A.

Two seasons ago, Samuel fished on another boat off Dutch Harbor and caught more fish than any other member of that boat.

• B.

Before becoming a fisherman, Samuel piloted a fishing boat whose members regularly caught record numbers of fish.

• C.

While fishing this past season, Samuel fell sick for a week and did not catch any fish during this time.

• D.

Unlike the other fishermen on his boat, at the order of the captain, Samuel fished this past season with experimental bait.

• E.

Amongst the fishing community in Dutch Harbor, Samuel has a reputation for being an especially bad fisherman.

D. Unlike the other fishermen on his boat, at the order of the captain, Samuel fished this past season with experimental bait.
Explanation
The fact that Samuel fished with experimental bait weakens the argument because it introduces a potential variable that could have affected his catch. It is possible that the experimental bait was not effective in attracting fish, which could explain why Samuel caught fewer fish than his teammates. This suggests that Samuel's poor performance may not be solely due to his fishing abilities, but rather a result of the circumstances and factors beyond his control.

### Virtually all health experts agree that second-hand smoke poses a serious health risk. After the publication of yet another research paper explicating the link between exposure to second-hand smoke and a shorter life span, some members of the State House of Representatives proposed a ban on smoking in most public places in an attempt to promote quality of life and length of lifespan. Which of the following, if true, provides the most support for the actions of the State Representatives?

• A.

The amount of damaging chemicals and fumes released into the air by cigarette smoke is far less than the amount released from automobiles, especially from older models.

• B.

Banning smoking in most public places will not considerably reduce the percent of the population in the state in question that smokes.

• C.

The state whose legislators are proposing the tough smoking legislation has a relatively high percent of its population that smoke.

• D.

Another state that enacted a similar law a decade ago saw a statistically significant drop in lung-cancer rates among non-smokers.

• E.

A nearby state up-wind has the highest number of smokers in the country.

D. Another state that enacted a similar law a decade ago saw a statistically significant drop in lung-cancer rates among non-smokers.
Explanation
This answer supports the actions of the State Representatives because it provides evidence of the positive impact of enacting a similar law in another state. The fact that there was a statistically significant drop in lung-cancer rates among non-smokers suggests that banning smoking in public places can effectively reduce the health risks associated with second-hand smoke. This information strengthens the argument for implementing a ban on smoking in most public places to promote a better quality of life and longer lifespan.

### Net Neutrality stipulates that Internet service providers (ISP) cannot partition their bandwidth such that different types of Internet communications have different maximum bandwidth capacities. For example, an ISP cannot relegate high bandwidth voice-over-IP (VoIP) traffic to a separate tunnel in an attempt to ensure that users of low-bandwidth functions such as plain-text email are not slowed down by the high-bandwidth users. Some individuals support implementing Net Neutrality on the principle that one group (i.e., users of high-bandwidth services) should not be effectively penalized for the actions of another group (i.e., users of slow-bandwidth services, who have a special traffic lane carved out for them, thereby slowing high-bandwidth users). Which of the following, if true, most seriously weakens the argument of the supporters of Net Neutrality mentioned above?

• A.

The jobs of many high-bandwidth users require these individuals to use high-bandwidth services.

• B.

Placing no restrictions on the bandwidth of individuals who use high-bandwidth services would force ISPs to purchase massive amounts of expensive additional bandwidth, disproportionately increasing the price of access for low-bandwidth users.

• C.

A strong and well respected lobbying firm recently revealed it has been hired by large telecommunications firms to oppose Net Neutrality on the grounds that it infringes upon a private company's ability to do business.

• D.

One country that mandated Net Neutrality saw a decrease in satisfaction of Internet users.

• E.

A recent court ruling upheld the principle that technology companies cannot discriminate in whom they serve or how they serve users.

B. Placing no restrictions on the bandwidth of individuals who use high-bandwidth services would force ISPs to purchase massive amounts of expensive additional bandwidth, disproportionately increasing the price of access for low-bandwidth users.
Explanation
If it is true that placing no restrictions on the bandwidth of individuals who use high-bandwidth services would force ISPs to purchase massive amounts of expensive additional bandwidth, this weakens the argument of supporters of Net Neutrality. It suggests that implementing Net Neutrality would result in a disproportionate increase in the price of access for low-bandwidth users, which goes against the principle of not penalizing one group for the actions of another. This undermines the argument that Net Neutrality is necessary to prevent the slowing down of high-bandwidth users by low-bandwidth users.

### Eating beets significantly lowers the risk of cancer, according to an article in a nutritional magazine. The article refers to a study that found that people who consumed one or more beets per day were half as likely to be diagnosed with the disease as people who did not. Which of the following, if true, most weakens the argument in the magazine article?

• A.

Another study found that people who consumed one tablespoon of flax seed oil per day were more than four times less likely to be diagnosed with cancer as those who did not.

• B.

Participants in the study reported consuming no vegetables other than beets.

• C.

The study was only conducted in one city.

• D.

In another experiment, cancer patients who ate one or more beets per day were no more likely to recover than those who ate no beets.

• E.

The participants in the study who ate beets were more likely to exercise regularly than those who did not eat beets.

E. The participants in the study who ate beets were more likely to exercise regularly than those who did not eat beets.
Explanation
This answer weakens the argument because it suggests that the lower risk of cancer could be attributed to the participants' exercise habits rather than their consumption of beets. It implies that exercise, not beets, may be the primary factor in reducing the risk of cancer.

### During the past 20 years, computer scientists focused increasingly on starting and running successful businesses. However, since businesses must be profitable, computer scientists must focus on developing products that generate profit. Consequently, computer science has lost its creative aspect. Which of the following assumptions is most necessary in order for the conclusion above to be drawn from the argument above?

• A.

All computer programs must lack creativity in order to be well received.

• B.

Some computer scientists entirely disregarded creativity and chose instead to pursue profit.

• C.

A program cannot be both creative and profitable.

• D.

Computer scientists are obsessed with the profitability of their work.

• E.

Non-profit institutions use large amounts of software.

C. A program cannot be both creative and profitable.
Explanation
The conclusion that computer science has lost its creative aspect is based on the assumption that a program cannot be both creative and profitable. This assumption is necessary because it implies that computer scientists must prioritize profitability over creativity, leading to the loss of the creative aspect in computer science. If it were possible for a program to be both creative and profitable, then the argument's conclusion would not hold true.

### Most scientists believe that the decay of the ozone layer is a cause of global warming. With a weaker ozone layer, additional wavelengths of light reach the earth. However, the danger posed by ozone decay is not limited to global warming. The decay of the ozone layer, which enables more harmful wavelengths of light to reach the earth's surface, is also believed to cause permanent eye damage in some animals. Which of the following is most strongly supported by the statements above?

• A.

All wavelengths of light from the sun that damage the eyes of animals are blocked by a healthy ozone layer.

• B.

Some animals do not experience damage to their eyes when exposed to unfiltered waves of light.

• C.

Only a handful of animal species live in places where they are exposed to the damaging light waves.

• D.

• E.

Some wavelengths of light that engender eye damage in certain animals are more likely to hit the earth due to ozone decay.

E. Some wavelengths of light that engender eye damage in certain animals are more likely to hit the earth due to ozone decay.
Explanation
The statement mentions that the decay of the ozone layer enables more harmful wavelengths of light to reach the earth's surface, which is believed to cause permanent eye damage in some animals. This supports the idea that some wavelengths of light that cause eye damage are more likely to hit the earth due to ozone decay.

### In an attempt to abate the pernicious decline in MicroChip's revenue brought about by shrinking demand that is accompanying an economic recession, MicroChip is offering customers a 50% discount for the next three months on all purchases fully paid for within 15 days. Which of the following assumptions most underlies the chip maker's offer of a discount?

• A.

MicroChip expects this discount to help the company retain existing customers and gain new ones, enabling the firm to survive in the long-term.

• B.

There are no other competing chip companies with prices lower than the reduced price.

• C.

The government will provide massive technology tax credits to businesses, spurring them to purchase chips and other related products.

• D.

The government will not pursue MircoChip if in fact its behavior in offering a deep discount amounts to a violation of predatory pricing laws.

• E.

The decrease in revenue brought about by the reduction in price will be smaller than the anticipated increase in revenue brought about by the increase in demand (spurred by the reduction in price).

E. The decrease in revenue brought about by the reduction in price will be smaller than the anticipated increase in revenue brought about by the increase in demand (spurred by the reduction in price).
Explanation
The assumption underlying MicroChip's offer of a discount is that the decrease in revenue caused by the reduction in price will be outweighed by the anticipated increase in revenue resulting from the increase in demand. In other words, MicroChip believes that the discount will attract enough customers to generate more sales and ultimately lead to higher overall revenue.

### Political Commentator: In order for a democracy to flourish, it is essential that political and journalistic freedom of expression exist. Even if commentators voice ideas that do not support the current government, a society is strengthened by the variety of views expressed. Yet, our government continues to exercise a stranglehold on certain forms of speech. It is essential that the government loosen its control on the media. Despite the potential short-term instability this may cause the country, it will strengthen the long-term health of the country. Which of the following expresses the conclusion of the argument?

• A.

The government is exercising too much control over the media

• B.

The government needs to open the media and release its hold on certain forms of speech

• C.

Democracy requires a strong and free press

• D.

Even ideas not supportive of democracy can strengthen a government

• E.

The future of the media lies in the hands of the government

B. The government needs to open the media and release its hold on certain forms of speech
Explanation
The conclusion of the argument is that the government needs to open the media and release its hold on certain forms of speech. This is evident from the statement that "It is essential that the government loosen its control on the media." The argument emphasizes the importance of political and journalistic freedom of expression in a democracy and suggests that despite potential short-term instability, it will strengthen the long-term health of the country.

### Years ago, some in the government's intelligence community feared the work of telecommunications researchers at then-emerging private security firms. The government experts concluded that these private firms posed the biggest risk to successful government espionage. As the private security firms began publicly releasing and advertising encryption algorithms and other security products, these government experts saw support for their conclusion when an encryption algorithm that government experts could not break began appearing in countless emails. Which of the following, if true, most weakens the conclusion of the government experts referred to above?

• A.

Shortly before the government experts reached their conclusions, two private security companies each claimed to have developed "the world's strongest email encryption algorithm"

• B.

The private security firms' decision to advertise their products and sell them publicly led to other members of the private sector and academia scrutinizing the encryption algorithms.

• C.

An open-source encryption algorithm, developed by an academic and freely available from popular websites, is recognized by numerous ex-government code breakers as the most unbreakable algorithm ever developed.

• D.

An enemy government recently succeeded in placing a spy within the government espionage operations referred to above.

• E.

To strengthen the reputation of the private security firms, employees of these firms publish information about the strength of their products and the benefits of using them.

C. An open-source encryption algorithm, developed by an academic and freely available from popular websites, is recognized by numerous ex-government code breakers as the most unbreakable algorithm ever developed.
Explanation
The statement that an open-source encryption algorithm, developed by an academic and freely available from popular websites, is recognized by numerous ex-government code breakers as the most unbreakable algorithm ever developed weakens the conclusion of the government experts. This suggests that there are other encryption algorithms available that are even more secure than the one being advertised by the private security firms. If there are stronger encryption algorithms out there, it undermines the claim that the private firms pose the biggest risk to government espionage.
