Hi CTG, How does the difficulty level of Quantitative on the actual GMAT compare with the quantitatives on the Kaplan exams?

I found these probability questions on this site. I could not figure out if the questions were correct. If they are indeed correct, I could not figure out how the solution is correct. How many 5 digit numbers can be created if the following terms apply: the leftmost digit is even, the second is odd, the third is a non even prime and the fourth and fifth are two random digits not used before in the number? a)2520 b)3150 c)3360 d)6000 e)7500 The answer for this seems to be A computer game has five difficulty levels. In each level you can choose among four different scenarios except for the first level, where you can choose among three scenarios only. How many different games are possible? a)18 b)19 c)20 d)21 e)None of the above The answer for this seems to be Any ideas?

Yeah I think something is missing as well. I have been hearing that the GMAT prep exams are the closest that you can get to the actual exams since they are prepared by the same people that prepare the actual exam. I have noticed some serious flaws in the questions in the software that cause unnecessary waste of time. Are the questions on the GMAT going to be clear and correct? Is PP better?

I got the 2nd question on my GMAT Prep Test. I think the question is wrong and should be what 2005 buster has mentioned below. Any comments?

If n and m are positive integers, what is the remainder when 3 ^ (4n + 2) is divided by 10. (1) n = 2 (2) m = 1 My answer was A. Can someone please explain why the OA is correct?

If there are no parenthesis, then D. If there are parenthesis (as Bob has indicated), I am not sure if you can say for sure. :hmm:

The question is: Is X/Y an integer Stmt 1 -> 3y^2 + 7Y = x => y(3Y + 7) = X => 3Y + 7 = X/Y SInce 3Y + 7 is an integer, X/Y is an integer. Sufficient Stmt 2 -> X (X-1)/Y is an integer. This does not mean X/Y is an interger. Take X = 3, Y = 6. Insuff Hence A

Its 3:2. Let English majors be 120 (some number divisible by 2 and 3). Then history majors - 60 and Math majors is 40.

Agree answer to 1 is C (I and II only) Answer to 2 is also C (3) It is simple when you remember that to find the number of factors we reduce to prime factors, add one to each of the powers of the prime factors and multiply the resulting powers.

Let X be the lowest populated district. Then the maximum populated district can be 1.1X. All the values of the rest of the 9 numbers should be within this range of X and 1.1X. Assume that all the other 9 values are 1.1X, then we have 10 district with a population of 1.1X and one with a population of X. So, X + 11X = 132000 12 X = 132000 => X = 11000

© and (E) are glaringly wrong. (A) uses a non-essential modifier:which, when an essential modifier such as "that" is necessary. Leaves me with B and D.

Bob, Agree with you that unambiguous pronoun reference has nothing to do with the nearest noun. Verb agreement in some cases is related to the nearest noun. If I understand your explanation correctly: an object pronoun (e.g. him, her, them, it, whom) will always refer to the object and as long as the reference to the object is unambiguous (clearly reference one of multiple objects if there are multiple objects) we are fine. If so, few of your examples seems to contradict this: Students in the metropolitan school district are so lacking in math skills that it will be difficult to absorb them into a city economy....Subject is "Students", Object is the gerund "Lacking" , Object Pronoun is them which according to your explanation should refer to lacking? Quasars are so distant that their light has taken billions of years to reach the Earth; consequently, we see them as they were during the formation of the universe Subject is "Quasars' light", Object is "Years", Object pronoun "them" should refer back to the object "Years". Am I missing something here?

Try numbers. Let p=5, n=1 , The reminder of (p+n)/5 =1. The reminder of (p-n)/3 is 1 The reminder of (p^2 - n^2)/15 is 9 Let p=9, n=2 , The reminder of (p+n)/5 =1. The reminder of (p-n)/3 is 1 The reminder of (p^2 - n^2)/15 is 2 Hence E

By a vote of 9 to 0, the Supreme Court awarded the Central Intelligence Agency broad discretionary powers enabling it to withhold from the public the identities of its sources of intelligence information. (A) enabling it to withhold from the public (B) for it to withhold from the public © for withholding disclosure to the public of (D) that enable them to withhold from public disclosure (E) that they can withhold public disclosure of The OG answer is . I would like to know why the OG answer does not have a pronoun reference error. Does "it" refer back to the Supreme Court or the CIA? Please respond with the rule to determine if the reference is sufficient.
