Everyone who has graduated from TopNotch High School has an intelligence quotient (IQ) of over 120. Most students with an IQ of over 120 and all students with an IQ of over 150 who apply to one or more Ivy League universities are accepted to at least one of them.
The statements above, if true, best support which of the following conclusions?
1]Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one IvyLeague school. We don't know if every graduate with an IQ of 150 applies to IvyLeague schools 2]If a person is a highschool graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School. Graduates of TopNotch are the relevant population. 3]If a person has an IQ of 130 and is attending an IvyLeague school, it is possible for him or her to have graduated from TopNotch High School. Since the stimulus says that most graduates of TopNotch who have an IQ above 120 and apply to IvyLeague schools get in, this is the best answer choice. 4]At least one graduate from TopNotch high school who has applied to at least one IvyLeague university has been accepted to one of them. We don't have enough information to say this. 5]If a highschool graduate has an IQ of 150 and is not attending an IvyLeague school, then he or she did not apply to one of them. We are discussing TopNotch highschool graduates.

The logic of using the technique is this: An assumption is a necessary missing premise. It is NECESSARY for the conclusion to hold. If the assumption is negated, the conclusion cannot hold. Hence, it is a check to see whether a statement is actually an assumption or not. Check out how to use the ANT here: http://www.veritasprep.com/blog/2013/03 ... thegmat/

what is the best approach to solve problems like these. I always find multiple options correct in these kind of questions and it is very diffucult to select correct one within 2 mins. Anybody can put down a sound approach to tackle problems like these ?? Thanks in advance.

Anybody can put down a sound approach to tackle problems like these ?? Thanks in advance. In must be true questions, if you are not sure whether the statement must hold, try to find a case where it may not hold. Try to make it false within the scope of the information given in the argument. Argument: Everyone who graduates from topnotch high school has IQ > 120. Most > 120 and all > 150 students who apply get accepted to at least one Ivy league university. For example, in option (B) above, B]If a person is a highschool graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School. Now try to make this false. Can we have a high school graduate with IQ 100 who could have been a student at TopNotch? The important point here is "could have been". Sure. Perhaps she graduated from another school but could have been a student here before that. So it needn't be true  it could be false. She could have been a student at TopNOtch. So this is not the answer.

The argument states that everyone who has graduated from Top Notch High school has an IQ over 120. "B" states that if a person is a high school graduate and has an IQ of 100, he or she could not have been a student at Top Notch High school. The case might be that this student studied in Top Notch High school for a while and the then shifted to some other school from where he graduated. In that case the conclusion does not hold. Hence "B" cannot be a possible answer

PathFinder007 wrote: Hi EMPOWERgmatRichCCould you please provide your comments on this. I want to know what is the issue with option B? Regards Hi PathFinder007, This is an Inference question. To be 100% clear on our assignment with this question, we have to be able to look at the correct option and say, "yup, I know that for an absolute fact." Let's pull up the salient points: Everyone who has graduated from TopNotch High School has an intelligence quotient (IQ) of over 120. Most students with an IQ of over 120 and all students with an IQ of over 150 who apply to one or more Ivy League universities are accepted to at least one of them. The statements above, if true, best support which of the following conclusions? B) If a person is a highschool graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School. Is it possible that TopNotch could have had STUDENTS (not graduates) with IQs of less than 100? Yes. From the information we're given, we can't rule out that possibility. For all we know, TopNotch could have had a student with a 99 IQ who got booted from the program and never graduated. That means we have to get rid of option B. Bigger Picture: There's a reason why this question is rated at a 95% difficulty quotient. The granularity of these options, particularly B, reaches an unusual level.

A) Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one IvyLeague school.
We can't conclude that every graduate of TopNotch with a 150+ IQ has APPLIED to an IvyLeague school. If they apply, the argument tells us that they will be accepted to at least one, but there's nothing in the prompt to suggest that every 150+ student applies to at least one Ivy.
D) At least one graduate from TopNotch high school who has applied to at least one IvyLeague university has been accepted to one of them.
Let's say that every TopNotch graduate who applies to an IvyLeague school has an IQ between 120 and 150 (so nobody with a 150+ IQ applies). We only know that MOST students with a 120+ IQ who apply to an IvyLeague school are accepted to at least one. Therefore, there exists the possibility that nobody from TopNotch would be accepted to an Ivy, so D has to be eliminated.
Hope that helps for those two choices! I am trying to understand why D) is incorrect. We know that "Most students with an IQ of over 120 who apply to one or more Ivy League universities are accepted to at least one of them" say 10 students from TopNotch high school (120<IQ<150) applied to one or more IVY league Universities, since most of them are accepted to at least one of them, we can expect at least 6(i.e. most of them) get accepted to one of the IVY leagues. I see that C is a clear answer. But I am not able understand why D is wrong.

I see that C is a clear answer. But I am not able understand why D is wrong. Here is why: Argument: Everyone who graduates from topnotch high school has IQ > 120. Most > 120 IQ and all > 150 IQ students who apply get accepted to at least one Ivy league university. 4]At least one graduate from TopNotch high school who has applied to at least one IvyLeague university has been accepted to one of them. Not necessary. It is possible that no student from top notch has IQ > 150 or even if there are students with IQ > 150, they may not have applied. We know that most students with IQ > 120 who apply get accepted but it is possible that all those who applied from top notch (and hence had IQ>120) got rejected. (Number of people who applied from top notch could be a very small % of the total number of people with IQ > 120 who applied) Say this year 1000 students with IQ greater than 120 applied to Ivy League universities. Say only 20 of them did not get accepted to any university so most got accepted. It is possible that all students of Top Notch who applied fall in this 20. What if only 5 of Top Notch had applied and all 5 are in this 20? Then (D) is not true.
