While on a straight road, Car X and Car Y are traveling at different constant rates. If car X is now 1 mile ahead of Car Y, how many minutes from now will Car X be 2 miles ahead of Car Y? (1) Car X is traveling 50 mph; Car Y is traveling 40 mph. (2) 3 minutes ago Car X was 1/2 mile ahead of Car Y.

(1) Shrinking distance problem: 50-40 = 10 mph*t=1 (2) We are told that 3 minutes ago Car X was 1/2 mile ahead of Car Y. Therefore, Car X took 3 minutes to get 1/2 mile ahead, or r3=1/2 --> r = 6 mph 6t = 1 mile --> t = 1/6 of an hour or 6 minutes THEREFORE, D. Growing distance you subtract the rates.

12 is divisible by 3 can be said in many different ways...

* 12 is a multiple of 3 * 12/3 is an integer *12 = 3n, where n is an integer *12 can be shared among 3 people so that each person has the same number of items *3 is a divisor of 12, or 3 is a factor of 12 *12/3 yields a remainder of 0 *3 "goes into" 12 evenly

If the problem states or assumes that a number is an integer, you may need to use prime factorization to solve the problem.

* determining whether one number is divisible by another number * Determining the greatest common factor of two numbers * Reducing fractions * Finding the least common multiple of two (or more) numbers * Simplifying square roots * Determining the exponent on one side of an equation with integrer constraints

What are factors and multiples?

*A number is a FACTOR of another numbers if it can be divided evenly into that number *A number x is considered to be a multiple of another number y, if y times an integer = x *Example - 15 is a multiple of 3 (3x5)

List divisibility rules

*Div by 2 if units digit can be evenly div by 2 *Div by 3 if sum of digits can evenly be div by 3 *Div by 4 if sum of last 2 digits can be div by 4 *Div by 5 if final digit is 0 or 5 *Div by 6 if div by 2 and 3 *Division by zero is undefined *Zero in numerator is fine; it equals zero

All evenly spaced sets are fully defined if the following are known...

*The smallest (first) or largest (last) number in the set *The increment (always 1 for consecutive integers) *The number of items in the set.

What are digits?

*There are 10 digits 0-9 *ALL integers are made up of digits *The digits can be different units in decimals; ones, tens, tenths, hundredths

Perfect Squares, Cubes, etc..

- All perfect squares have an odd total number of factors - The prime factorization of a perfect suqare contains only even powers of primes (Also true that any number whose prime factorization contains only even powers of primes must be a prime number) - If a numbers prime factorization contains any odd powers of primes, then the number is not a perfect square

For any set of consecutive integers with an EVEN number of items, the sum of all the integers is NEVER a multiple of the number of items.

...

For any set of consecutive integers with an ODD number of items, the sum of all the integers is ALWAYS a multiple of the number of items.

...

If you add or subtract two multiples N, you get another multiple of N

If the length of side AB is 17, is triangle ABC a right triangle? (1) The length of side BC is 144. (2) The length of side AC is 145.

According to the Pythagorean Theorem, in a right triangle a2 + b2 = c2. (1) INSUFFICIENT: With only two sides of the triangle, it is impossible to determine whether a2 + b2 = c2. (2) INSUFFICIENT: With only two sides of the triangle, it is impossible to determine whether a2 + b2 = c2. (1) AND (2) SUFFICIENT: With all three side lengths, we can determine if a2 + b2 = c2. It turns out that 172 + 1442 = 1452, so this is a right triangle. However, even if it were not a right triangle, this formula would still be sufficient, so it is unnecessary to finish the calculation. The correct answer is C.

Which of the following would result in a remainder of 7 when divided by 12? I. 151 II. 3,443 III. 5,995 I only I and II I and III II and III I, II and III

I. TRUE: 151 - 7 = 144. 44 is divisible by 4, and the sum of the digits of 144 is 9, which is divisible by 3. II. FALSE: 3,443 - 7 = 3,436. Because 36 is divisible by 4, the number 3,436 must also be divisible by 4. However, the sum of digits of 3,436 is 16, and 16 is not divisible by 3. III. TRUE: 5,995 - 7 = 5,988. 88 is divisible by 4, and the sum of the digits of 5,988 is 30, which is divisible by 3. The correct answer is C.

Disguised Postive & Negative Example

If (a-b) / c < 0, is a>b ? 1) c> 0 2) a+b < 0 The fact that (a-b)/ c < 0 tells you that a-b and c have different signs. Thus one expression is positve and the other is negative. Stmt 1: tells you that c is negative, therefore a- b must be positive. Sufficent Stmt 2: Says that sum of a and b is negative. doesnt tell you weather a is lager than b. Insufficent.

Stick Separator Method (same gifts or items)

If 16 oranges are distributed among 4 children such that each gets at least 3 oranges, the number of ways of distributing them is a. 30 b. 210 c. 15 d. 35 e. 40 Number of grouping simply becomes number of ways to arrange remaining 4 oranges and 3 separators between themselves = (4 + 3)!/(4!*3!) = 35

Factor Foundation Rule

If a is a factor b, and b is a factor of c, then a is a factor of c. Or, any integer is divisible by all of its factors and it is also divisible by all all the factors of its factors.

What is a remainder?

If a number cannot be evenly divided by another number, the number left over at the end of the division is called the remainder.

Non-terminating Decimals

Wes works at a science lab that conducts experiments on bacteria. The population of the bacteria multiplies at a constant rate, and his job is to notate the population of a certain group of bacteria each hour. At 1 p.m. on a certain day, he noted that the population was 2,000 and then he left the lab. He returned in time to take a reading at 4 p.m., by which point the population had grown to 250,000. Now he has to fill in the missing data for 2 p.m. and 3 p.m. What was the population at 3 p.m.? 50,000 62,500 65,000 86,666 125,000

If we decide to find a constant multiple by the hour, then we can say that the population was multiplied by a certain number three times from 1 p.m. to 4 p.m.: once from 1 to 2 p.m., again from 2 to 3 p.m., and finally from 3 to 4 p.m. Let's call the constant multiple x. 2,000(x)(x)(x) = 250,000 2,000(x3) = 250,000 x3 = 250,000/2,000 = 125 x = 5 Therefore, the population gets five times bigger each hour.At 3 p.m., there were 2,000(5)(5) = 50,000 bacteria. The correct answer is A.

Critical Reasoning - assumption question

In an assumption question, the key thing to realize is that you are not looking for the answer choice that does the most for the stimulus when added - you are looking for the answer choice that hurts the most when taken away. The correct answer to an assumption question is something that is "necessary" to the argument. For example, taking the GMAT is necessary for acceptance into most MBA programs. If you take the GMAT away, then the conclusion - being accepted into a MBA program - is harmed. An assumption is not something that has to really strengthen the conclusion when added. For example, just taking the GMAT does not guarantee admission into an MBA program.

Remainders

Q: If a/b yields a remainder of 5, c/d yields a remainder of 8, and a,b,c and d are all integers, what is the smallest possible value for b+d? A: Since the remainder must be smaller than the divisor, 5 must be smaller than 5 b. b must be an integer, so be is at least 6. Similarly, 8 must be smaller than d and d must be an interger so d must be atleast 9.Therefore, smallest possible value for b+d is 6+9=15 ** Remainder cannot be greater than divsor or negative, must adjust for excess by taking out the divisor from the remainder or adding the divisor to the remainder (when is negative)

Remainders contd...

The decimal of a quiotent is the remanider and must be an integer. Moreover, the decmial part of the quiotent can be multipled by the divisor to get the intger remainder. Ex: 7/5 = 1.4.... (.4)*5=2.0 (2 is the integer version of the remainder)!

If (x # y) represents the remainder that results when the positive integer x is divided by the positive integer y, what is the sum of all the possible values of y such that (16 # y) = 1? 8 9 16 23 24

The definition given tells us that when x is divided by y a remainder of (x # y) results. Consequently, when 16 is divided by y a remainder of (16 # y) results. Since (16 # y) = 1, we can conclude that when 16 is divided by y a remainder of 1 results. Therefore, in determining the possible values of y, we must find all the integers that will divide into 16 and leave a remainder of 1. These integers are 3 , 5, and 15. The sum of these integers is 23. The correct answer is D.

of (accuse of)

The politician was accused ___ being economical with the truth

Bill runs a hot dog stand, and at the end of the day he has collected an assortment of $1, $5, and $10 bills. He discovers that the number of $1, $5, and $10 bills that he has is in the ratio of 10 : 5 : 1, respectively. How many $10 bills does he have? (1) The dollar value of his $1 bills equals the dollar value of his $10 bills. (2) Bill has a total of $225.

The question stem tells us that Bill has a stack of $1, $5, and $10 bills in the ratio of 10 : 5 : 1 respectively. We're trying to find the number of $10 bills. (1) INSUFFICIENT: Since the ratio of the number of $1 bills to $10 bills is 10 : 1, the dollar value of the $1 and $10 bills must be equal. Therefore statement (1) gives us no new information, and we cannot find the number of $10 bills. (2) SUFFICIENT: The problem states that the number of $1, $5, and $10 bills is in the ratio of 10 : 5 : 1, so let's use an unknown multiplier x to solve the problem. Using x, we can see that there are 10x $1 bills with a value of $10x. Furthermore, there are 5x $5 bills with a value of $25x. Finally, there are 1x $10 bills with a value of $10x. Statement (2) says that the total amount he has is $225, so we can set up an equation as follows: $10x + $25x + $10x = $225 $45x = $225 x = 5 Since there are 1x $10 bills this means that there are 5 $10 bills. The correct answer is B.

We are puzzled as ___ how it happened

Bag A contains red, white and blue marbles such that the red to white marble ratio is 1:3 and the white to blue marble ratio is 2:3. Bag B contains red and white marbles in the ratio of 1:4. Together, the two bags contain 30 white marbles. How many red marbles could be in bag A? 1 3 4 6 8

We are told that bag B contains red and white marbles in the ration 1:4. This implies that WB, the number of white marbles in bag B, must be a multiple of 4. What can we say about WA, the number of white marbles in bag A? We are given two ratios involving the white marbles in bag A. The fact that the ratio of red to white marbles in bag A is 1:3 implies that WA must be a multiple of 3. The fact that the ratio of white to blue marbles in bag A is 2:3 implies that WA must be a multiple of 2. Since WA is both a multiple of 2 and a multiple of 3, it must be a multiple of 6. We are told that WA + WB = 30. We have already figured out that WA must be a multiple of 6 and that WB must be a multiple of 4. So all we need to do now is to test each candidate value of WA (i.e. 6, 12, 18, and 24) to see whether, when plugged into WA + WB = 30, it yields a value for WB that is a multiple of 4. It turns out that WA = 6 and WA = 18 are the only values that meet this criterion. Recall that the ratio of red to white marbles in bag A is 1:3. If there are 6 white marbles in bag A, there are 2 red marbles. If there are 18 white marbles in bag A, there are 6 red marbles. Thus, the number of red marbles in bag A is either 2 or 6. Only one answer choice matches either of these numbers. The correct answer is D.

If 72 cupcakes must be divided equally among the students in a certain class, how many students are in the class? (1) If the number of students is reduced by one-third, each student will receive 3 more cupcakes. (2) If the number of cupcakes is doubled, each student will receive 12 cupcakes.

We can begin by rephrasing the question; because we know that the 72 cupcakes must be shared equally among the students, we must have the following relationship: We can pick variables to represent both the number of students and the number of cupcakes each student will get: let s represent the number of students, and let p represent the number of cupcakes per student. Thus, we have the following equation: The original question asked for the value of s. Solving for s, we can rephrase this question as "what is 72/p?" Thus if we can determine the value of s directly or p we have sufficient data to answer the question. (1) SUFFICIENT: If the number of students is reduced by one-third, then two-thirds of the students will remain; the new number of students would therefore be (2/3)s. In this scenario, each student would then receive 3 more cupcakes, or p + 3 cupcakes each. Translating the general equation from the stem using this new information yields the following equation: Substituting the equation, p = 72/s, from the stem into the equation from statement (1) yields: (2) SUFFICIENT: If there are twice as many cupcakes, then there are 144 cupcakes and each student will receive twelve of them, so we know p = 12. Translating the statement yields the following equation: # of cupcakes = (# of students) × (# of cupcakes per student) 144 = s(12) s = 12 The correct answer is D.

What is the sum of the digits of the positive integer n where n < 99? 1) n is divisible by the square of the prime number y. 2) y4 is a two-digit odd integer.

We cannot rephrase the given question so we will proceed directly to the statements. (1) INSUFFICIENT: n could be divisible by any square of a prime number, e.g. 4 (22), 9 (32), 25 (52), etc. (2) INSUFFICIENT: This gives us no information about n. It is not established that y is an integer, so n could be many different values. (1) AND (2) SUFFICIENT: We know that y is a prime number. We also know that y4 is a two-digit odd number. The only prime number that yields a two-digit odd integer when raised to the fourth power is 3: 34 = 81. Thus y = 3. We also know that n is divisible by the square of y or 9. So n is divisible by 9 and is less than 99, so n could be 18, 27, 36, 45, 54, 63, 72, 81, or 90. We do not know which number n is but we do know that all of these two-digit numbers have digits that sum to 9. The correct answer is C.
