Bracelets cost p dollars each at a discount store. At a neighboring retail chain store, the same bracelets cost $1 more each, which means that x dollars will buy 10 more bracelets at the discount store than at the retail chain store. What is the value of x in terms of p? 10 (p+1) 10 (p-1) 10 (p^2 + p) 10 (p^2 - p) 10 (p^2 + p + 1)

10 (p^2 + p)

If the cost per unit of item A increases by r percent and the profit per unit of item A decreases by s percent, where s > r, then in terms of r and s, by what percent is the ratio of profit per unit to cost per unit decreased? r/s 100 (r-s) / 100 + r 100 (s+r) / 100 + r 100 (r+s) / 100 + s 100 (s-r)/ 100 + s

100 (s+r) / 100 + r

Thirty percent of the balloons used to decorate a party are red and the rest are yellow. If one-quarter of the yellow balloons have strings and there are a total of 40 balloons, how many of the yellow balloons do not have strings? 6 7 12 18 21

A group of friends on a hoke split up into smaller groups. When they formed groups of three, one person was left out. When they formed groups of four, two people were left out. When they formed groups of six, four people were left out. If the group contains at least a dozen people, what is the smallest possible number of people in the group? 10 20 22 26 34

22 (Can't be 10 since it is at least a dozen. If when they split up in groups of 4, there were 2 person left, it means the remainder is 2. So take the middle option and strat working from there. 22 divided by 4, the quotient is 5 and remainder is 2)

In 2015, sales at Company X were 20% less than its sales in 2014. In 2016, sales were 30% greater than sales in 2015. By what percent did company X sales change from 2014 to 2016? 10% decrease 4% increase 5% increase 10% increase 56% increase

(6^2)*(5^3)*(2^4)/120^2 = 4 5 6 10 30

5 (Find common factor of 120 with all the numerators. So 120 equals 6 * 5 * 2^2. Rewrite the equation and cancel out 6^2 and 2^4. So the simplified equation is 5^3/5^2 = 5)

If a represents a single digit and the four-digit integer a12a is divisible by 6, what is a? 2 3 4 6 7

6 (Start taking away options. If a number is divisible by 6, it must be divisible by 2 and 3, and if it is divisible by 2 it means it must be even. So it can be either 2122, or 6126; and 6126 is divisible by 6)

If X<0, which of the following statements must decrease as x decreases? I. 10x-100 II. (x-1)/x III. x^2 - x I only III only I and II I and III II and III

I and II (Consider each step separately. Statement I, with every unit decrease in x, 10x decreases by 10 units. This statement must decrease as x decreases. Statement II, as x decreases, the numerator is always 1 more than the denominator so the expression gets closer to 1. The closer that X is to 0 (the higher x), the greater the result. So as x decreases so does the equation. No need to evaluate Statement III)

square root of 99 - square root of 44 + square root of 11 = a. Square root of 11 b. 2 * Square root of 11 c. Square root of 66 d. 12 e. 6 * Square root of 11

b. 2 * Square root of 11

If the product of integer m and integer n is odd, then which must be even? n/m m-n m+2n m/n - 1 2 *(m/n)

m-2 (If the product of m and n is odd, it means both m and n are odd. An odd number minus an odd number must be even. Remember decimals can not be either even or odd, so answer must be an integer)

If x(p+q) = x and x<>0, which of the following must be true? p=q p>q p+q=0 q=1-p q=p-1

q=1-p (Since x cant be 0, divide both sides of the equation by x to leave p+q=1. This can also be written as p = 1 -q or as in option D q=1-p)

If n-rs = n and r<>0, which of the following must be true? r=1 r=s r+s=0 |rs| = 1 s=0

s=0 (Solve for r. The equation equals -rs=0, so rs = 0. If the product is 0, one of them must be 0.)'\

If -3<=X<=1, which if the following inequalities is an algebraic expression for the shaded part of the number line above? |x| <= 1 |x| <= 3 |x-1| <= 2 |x+1| <= 2 |x-2| <=1

|x+1| <= 2 (If x<=1, then |1+1| <= 2, and that is the maximum value of x)

(3^3+ 3)/3 + (3^2+3^2)/3^2 = 1 5 12 17 30

Alicia scored an A on 30% of her first g tests during the semester. Deciding to improve her grade, alicia works hard and scores an A on each of her remaining h tests during the same semester. If Alicia scored an A on 50% of her tests over the entire semester, which of the following expresses the ratio of g to h? 1:3 2:5 3:5 5:2

5:2

On a certain day, a movie theater is playing all 3 parts of a trilogy. Part 1 plays every hour, beginning at 10am and lasts 2 and 1/4 hours. Part 2 plays every 1 and a half hours, beginning at 10a, and lasts 2 hours. Part 3 plays every 1 and a half hours beginning at 12:15pm. What is the least total amount of time a person planning to watch all 3 parts in roder must spend waiting between movies? 15 min 30 min 45 min 60 min 90 min

30 min (There are three options to start with Part 1. I. Start at 10am and finish at 12:15. Then at 1:00pm to 3:00pm. Then at 3:15 pm. So the person would wait 45 min + 15 min = 60 minutes. II. Start at 11am and finish at 1:15. Then 2:30 pm to 4:30pm. Then at 4:45. So the person would wait 75 min + 15 min = 90 minutes III. Strat at 12pm until 2:15. Then 2:30 to 4:30. Then 4:45. So the person would wait 15 min + 15 min = 30 min Option 3 is the least amount of time)

In the range of numbers from 1 to 200, how many numbers will contain 3 as at least one of its digits? 19 20 30 38 40

38 (The number 3 appears 10 times as the units digit between 1 and 100 (3,13,23,33,43,etc). Then it also appears 10 times as the tens digit in all numbers 30 (30,31,32,33,etc). In these two sets, the number 33 is repeated, so the total number of times when 3 is at least once would be 10+10-1 = 19. So between 1 to 200, it would be 19+19=38 numbers)

Which of the follwowing is the largest? 11/27 5/9 1/3 25/81 3/20

5/9 (Two ways: I. B is the only choice where the numerator is more than half of the denominator so it must be the biggest. II. Obvious choices that are too small like 3/20 and 25/81. So you can cross multiply the other choices to see which one is bigger. Start with 1/3 and 5/9 = 9<15, so 1/3 < 5/9. And then 5/9 with 11/27, 135>99, so 5/9>11/27. So 5/9 is the biggest)

If 8*3^7 = 3^x - 3^x-2, what is the value of x? 1 3 7 9 12

9 (Rewrite the right side of the equation as 3^x - (3^x)*(3^-2). The factor out 3^x from the right side, (3^x)(1-3^-2) = (3^x)(1-1/9) = (3^x)(8/9). Then divide both equations by 8, so 3^7 = 3^x/9, 3^7 = 3^x/3^2, 3^7 = 3^x-2. Now that the bases are equal, operate the exponents, 7 = x-2, x = 9)

During the first hour of a day, a stationary store sells only $1.50 worth of envelopes, $2.25 worth of pens, and a three-ring binder for $5.25. If the store had $20 in the cash register at the beginning of the day, and the store charges 8 percent sales tax on all purchases, how much money is in the register at the end of the first hour? $29.72 $27.92 $20.72 $9.72 $7.92

$29.72

Expression: (a^2 + b)/(b-a) In the expression above, if a <> b, and a is replaced with -b, the reciprocal of the resulting expression is equal to: (1+b/2) (2/1+b) (1-b/2) (2/1-b)

(2/1+b)

If k = 5p, where p is a prime number greater than 2, how many different positive even divisors does k have, including k? 0 1 2 4 5

0 (Assume p=3, so k=15. Divisors of 15 are 1,3,5, and 15. None are even so it is 0. Also remember 2 is the only even prime number, so if p is greater than 2, it cannot be divisble by an even number)

If m,n and p are constants, m<n<p, and y^3- y = (y+m)(y+n)(y+p) for all numbers y, what is the value of n? -3 -1 0 1 3

0 (Factor the left side of the equation to put it into a form equivalent to (y+m)(y+n)(y+p): y^3-y = y(y^2-1) = y(y-1)(y+1) = (y+0)(y-1)(y+1) So the values are -1,0 and 1. The question states that m<n<p, so the values are m=-1, n=0, and p = 1.

(-4*3)^4/(12*6*2)^2

If x is an integer, then what is the least possible value of |99-7x|? 0 1 5 98 107

1 (We are looking to how close to 0 we can get. What number multiplied by 7 gets the closest to 99 but is still less than 99. The number is 14, |99-7(14)|= |99-98|= 1)

If k is a positive integer and the ratio of s to r is equivalent to k/1000, then r is what percent of s, in terms of k? 1000k 1/1000k 1/10k k/100 100000/k

100000/k

Two solutions are made by adding Chemical Z to water. Solution A is 40% Chemical Z and Solution B is 80% Chemical Z. A chemist combines Solution A and Solution B to make a mixture. If x percent of the Chemical Z in the combined mixture comes from Solution A, and if y percent of the total volume of the mixture comes from Solution A, which of the following expresses x in terms of y ? 60y/80-y 100y/200-y 120y/200-y 200y/240-y

To entice purchase of the membership at the new price, a 20 percent discount is offered. If Jim buys his membership this month, how much will he pay as a percent of price G ? 90% 97% 104% 110% 125%

104%

One-fifth of the students at a nursery school are 4 years old or older. If 16 students have not yet reached their third birthday, and a total of 40 students are not between 3 years old and 4 years old, how many children are in the nursery school? 120 96 70 60 24

120

In 1990, those who invested money in fund Z for the entire year received a return of 9 percent on their investment. Roberta invested a certain amount in fund Z on January 1, 1990, and neither added to nor subtracted from her investment during the year; her investment and return for the entire year equaled $15,260. How much money did Roberta invest in fund Z on January 1, 1990? 13000 13260 14000 14360 14750

14000

y | (0,8) B | (0,3) A | | _ _ _ _ 7 _ _ _ _ _ _ _ _ _ _ _ x In the coordinate plane above, if line 1 || line 2 || x-axis and point a on line 2 is exactly 13 units away from point b on line 1, what is the x-coordinate of point b ? 19 17 15 12 8

If non-negative integers n and p are not both odd, which of the following must be odd? np np+2 2n+p 2(n+p) 2(n+p)+1

2(n+p)+1 (If they are not both odd, they are both even or one of them is even. Numbers are even if they are a factor of 2. Take option (E), if the sum of ANY two numbers in multiplied by 2. The result will always be even. Then if you add 1, it will always be odd)

If two positive integers x and y are not both even, then which of the following must be odd? xy x+y x-y x+y+1 2(x+y)+1

2(x+y)+1 (When multiplied by 2, any sum between any two numbers will be a multiple of 2 so it is even. If you add 1 it will be odd)

Running at the same constant rate, n printing presses can produce a total of 150 newspapers per minute. At this rate, how many newspapers could xsuch machines produce in 90 seconds? 13500/NX 225X/N 150X/N 90X/N 5XN/2

225X/N

In an office there are 4 female staff members and 10 male staff members. In how many ways can a committee of 3 members be formed if it must include at least one female member? 120 244 364 1464 2184

244 (First find the combination of all 14 members, 14C3 = 364. Then find how many committees can be formed only with the men, so 10C3 = 120. Then substract 364-120=244)

A committee consisting of 5 members is to be formed out of 6 men and 4 women. How many committees can be formed so that at least one woman is always in the committee? 252 300 867 123 246

246 (First combination of 10C5 = 252. Then find number when only men are chosen, 6C5 = 6. Then substract 252-6 =246)

If positive integers x and y are not both even, which of the following must be odd? x/y 3xy 2xy-1 x+y x-y

2xy-2 (If they are not both even, it means one of them is odd or both of them are odd. Any two numbers multiplied by 2 will be even, so if you substract 1, it will always be odd)

If a and b are two positive integers whose greatest common divisor is 1, what will be the remainder of a/b, if a/b = 3.75? 1 2 3 4 5

3 (You can rewrite 3.75 as 3/4 + 3, or 3(3/4). The remainder is the numerator in the fraction, so the remainder is 3)

How many even numbers in the range between 10 and 100, inclusive, are not divisible by 3? 15 30 31 33 46

31 (To be divisible by 3, it must be odd or divisible by 6. So the number of even numbers between 11 and 99 is (99-11)/2 = 44+2 (inclusive of 10 and 100) = 46. Then, the first number divisible by 3 is 12, and the last number is 96. So (16-2)+1=15 multiples of 6 between 10 and 100. So total numbers not divisible by 3 are 46+15=31)

A company produces baseball cards in equal numbers of regular packs of 16 and deluxe edition packs of 30. If, on a certain day, a company produces 241 cards, what is the smallest number of additional cards the company needs to produce in order to maintain its regular production practice? 5 11 21 35 46

The flow of water through a drainage pipe was monitored for a 3-hour period. In the second hour, the rate of flow was 15 gallons per hour, which was 50 percent faster than the rate of flow for the first hour. If 25 percent more water flowed through the pipe in the third hour than it did in the second, how many gallons of water flowed through the pipe during the entire three hours? 41.25 42.5 43.75 45 57.5

43.75

How many integer values of a satisfy the inequality |a-5| <=2.5? 3 4 5 6 7

5 (Factor the inequality to -2.5 <= (a-5) <= 2.5. Then add 5 to isolate a, return 2.5<=a<=7.5. The possible integers would be 3,4,5,6,7)

It would take one copyist 10 minutes to copy a large document and another copyist 12 minutes to copy the same document. How many minutes would it take both copyists, working simultaneously at their respective constant rates, to copy the document? 11/60 5 5 5/11 11 22

5 5/11 (Two ways: I. One copyist rate is 1/10 of a document per minute and the other 1/12 of the document per minute. So together, it would be 1/10 + 1/12 = 6/50+5/60 = 11/60 of the document per minute. So it would take them the reciprocal, 60/11 minutes, to complete the whole document. II. Together, it will take them about half their times to copy the document. So 10/2 = 5 and 12/2 = 6. So it will take both copyists together between 5 and 6 minutes to copy the whole document. Option C is the only one between this range)

If m is a positive integer and q+4 = 7^m, which of the following could NOT be a value of q? 3 45 54 339 2397

54 (The question says that q-4 has to be a multiple of 7. So 7-4 = 3, 49-4=45, 56-4=52 but the option says 54 so it is incorrect. Also, 54 is the only even number. Because m is positive, 7^m will always be odd. This means that q+4 must be odd, and in order for q+4 to be odd, q must be odd)

State | 1980 | 1990 Washington 12% 10% Oregon 17% 17% Iowa 9% 13% Vermont 20% 15% Maine 9% 12% California 33% 33% Total | 1.2 B | 1.6 B The increase in the number of matches produced in California from 1980 to 1990 exceeds by how many million the increase in the number of matches produced in Oregon over the same period? 68 64 16 2.56 1.82

If 5a + 2b = 11 and 4a + 3b = 4, then a - b = -7 25/7 48/7 7 15

If n = 3*4*p, where p is a prime number greater than 3, how many different positive non-prime divisors does n have, excluding 1 and n? 6 7 8 9 10

7 (Assume p =5, so n = 60. Go down the list starting with 1 until you find the number that multiplied by 10 equals n. So 1*60, 2*30, 3*20, 4*15, 5*12, 6*10. Now exclude all primer divisors and 1 and n. So you are left with 4,6,10,12,15,20,30.)

if Square root of a = 3 and square root of b = 4, then square root of a + square root of b/ square root of a+b = a. 1 b. 8/7 c. 7/5 d. 12/5 e. 5

7/5

How many integers that have a value less than 4 satisfy the inequality (y+1)(y+2)(y+4)>=0? 4 5 6 7 8

8 (If y < 4, the max value of y is 3. Going down the line you can go until -4 before the result is negative. With -4, (-4+1)(-4+2)(-4+4)=(-3)(-2)(0). 0>=0. The lowest number would be when the biggest product (4) equals 0)

The Amazing soft drink company interviewed c consumers for a market research. The study found that ⅖ of consumers preferred Zing Cola to Diet Zing Cola. Of those who preferred Diet Zing, ⅙ preferred Caffeine Free Diet Zing. How many consumers in terms of c, did not prefer Caffeine Free Diet Zing? c/11 c/10 7c/15 9c/10 10c/11

9c/10

If A=-2.3, B=-0.8, C=0, D=1.3, E=2. Which of the following points has the second least absolute value? A B C D E

B (C is 0 so it is the least absolute value. Determine what is the next value closest to 0. The distance from 0 to B is less than 1 (0.8) so that is the second least absolute value)

A circular patch is placed on a square piece of fabric. What is the perimeter of the square piece of fabric? (1) The radius of the patch is 4 centimeters. (2) Each side of the square piece of fabric is tangent to the patch. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. EACH statement ALONE is sufficient. Statements (1) and (2) TOGETHER are NOT SUFFICIENT

BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

If A is a positive integer, is A a multiple of 30? I. A is a multiple of 20 II. Square root of A is a multiple of 24 Statement 1 ALONE is sufficient, but statement 2 is not Statement 2 ALONE is sufficient, but statement 1 is not Both statements TOGETHER are sufficient Each Statement ALONE is sufficient Statements 1 and 2 together are NOT sufficient

Both statements TOGETHER are sufficient (I. There are multiples of 20 that are also multiples of 30 (60, 120, etc) but there are also many that are not multiples of 30 (20,40,80, etc). So it is not sufficient. II. A multiple of 30 must contain all the prime factors of 30: 2,3, and 5. If A is a multiple of 24^2 or (2*2*2*3)^2 but it does not contain 5 so it is not sufficient. But together, it says that if A is a multiple of 20 and is also a factor of 2,3, and 5, it will always be a multiple of 30. So together, they are sufficient)

A certain restaurant regularly orders tomatoes, pasta, and cheese. The number of pounds of tomatoes ordered, t, is directly proportional to the number of pounds of pasta ordered, p, which in turn is directly proportional to the number of pounds of cheese ordered, c. If t = 150, then what is the value of c ? t = 300 whenever p = 900. p = 300 whenever c = 8 Statement 1 alone is sufficient, but statement 2 alone is not sufficient Statement 2 alone is sufficient, but statement 1 alone is not sufficient Both statements together are sufficient, but neither statement alone is insufficient Each statement alone is sufficient Statements 1 and 2 together are not sufficient

Both statements together are sufficient, but neither statement alone is insufficient

Bill went shopping for fruits and vegetables. He purchased a number of potatoes, onions and lemons in the ratio of 1:3:5, respectively. How many potatoes did Bill buy? I. Bill bought a total of 27 potatoes, onions and lemons II. Bill bought 9 onions Statement 1 ALONE is sufficient, but statement 2 is not Statement 2 ALONE is sufficient, but statement 1 is not Both statements TOGETHER are sufficient Each Statement ALONE is sufficient Statements 1 and 2 together are NOT sufficient

Each Statement ALONE is sufficient (Statement 1 says p+o+l= 27. The question says the ratio is 1+3+5=9. Divide 27 by the number of parts of the ratio and it is sufficient. Also can solve with the equation x+3x+5x=27. It is sufficient. Then statement 2, if we know the quantity of one item purchased we can find the other values with the ratio. Also if Bill bought 9 onions and x is the number of potatoes, solve for 9=3x, x =3. Both statements are sufficient)

All of the 121 baseball players participating in a celebrity golf outing were born in either Asia, Australia, North America, or South America. If there are 25 percent fewer players that were born in Australia than were born in Asia, how many of the participating players were born in North America? The number of players who were born in South America is 40 percent greater than the number of players who were born in Asia. The ratio of the number of players who were born in North America to the number of players who were born in South America is 29:14.

Of the 1200 members of a gym, 150 have student memberships and attend fitness classes 2 or more times a week. How many of the 1200 members have students memberships and attend fitness classes fewer than 2 times a week?

Statement 1 ALONE is sufficient, but statement 2 is not (I. If 800 members have non-student memberships, it means that 400 members have student memberships. The questions says that out of those 400, 150 attend classes 2 or more times a week, so 250 attend 2 or less times a week. It is sufficient. II. It states the total number of members who attend classes less than 2 times a week, but does not say how many of those 650 have student membership.)

What is the value of (8a+a-b)/a-b? I. 5a+4b/a-b = 2 II. a - b = 9 Statement 1 ALONE is sufficient, but statement 2 is not Statement 2 ALONE is sufficient, but statement 1 is not Both statements TOGETHER are sufficient Each Statement ALONE is sufficient Statements 1 and 2 together are NOT sufficient

Statement 1 ALONE is sufficient, but statement 2 is not (Solve the equation is statement 1 for a = -2b. Then use this to replace in the question formula to solve for b. 9(-2b)-b/-2b-b = 19/3. Then you can replace to find the value of a, but you dont have to and you already know it is sufficient. Statement 2 states that a = b+9. If you also substitute in the equation you get 8b+81/9, so it is not sufficient)

If a and b are positive integers, what is the remainder when 4^(a+1+2b) is divided by 10?

Statement 1 ALONE is sufficient, but statement 2 is not (when 4^n is divided by 10, a remainder equal to the units digit of the value results. So: 4^1 / 10 = remainder is 4 4^2 /10 = remainder is 6 4^3 / 10 = remainder is 4 4^4 / 10 = remainder is 6 So for all n that is odd, the remainder is 4. And for all n that is even, the remainder is 6. Since 2b will always be even, knowing that a is odd, means that a+1 will always be even and the remainder will always be 4. So statement 1 is sufficient. With statement 2, we still would not know the value of a, and it is needed to determine whether or not the exponent will be even or odd)

A journalist is writing an article on the 100 members of the United States Senate. After researching her article, the journalist classifies the Senators into one of four categories: men who have earned at least one college degree, men who have not earned a college degree, women who have earned at least one college degree, and women who have not earned a college degree.
