A. Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.
>> To be sure we need an IQ of more than 150 ... not just 150 ... drop

B. If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.
>> he could be a student of TN highschool ... but he wont graduate from it ... drop

C.If a person has an IQ of 130 and is attending an Ivy-League school, it is possible for him or her to have graduated from TopNotch High School.
>> Keep it ... it is quite possible

D.At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.
>> drop it .....

E.If a high-school graduate has an IQ of 150 and is not attending an Ivy-League school, then he or she did not apply to one of them.
>> we can not say for sure ... may be he applied and got selected also ... but chnaged his mind and not attending becuase of other reasons .... drop it

Most of the student with IQ over 120, and all students with IQ over 150 gets accepted.
All gradutae from Topnotch school has IO over 120.

==> Most students from top notch high school gets accepted.

The statements above, if true, best support which of the following conclusions?

A. Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.

Wrong. IQ = 150 is not sure but IQ more than 150 has 100% chance of getting accepted in atleast 1 student.

B. If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.

Out of scope.

C.If a person has an IQ of 130 and is attending an Ivy-League school, it is possible for him or her to have graduated from TopNotch High School.

Correct. (over 120 IQ)

D.At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.

Wrong 'its mostly'.

E.If a high-school graduate has an IQ of 150 and is not attending an Ivy-League school, then he or she did not apply to one of them.

Wrong. probably he/she is not passed out of TOPnotch high school.

IMO C

i agree with the answer, but i dont agree with your reason for rejecting E.... no where it says that to get a sure selection both IQ >150 and passed out from TopNotch is required.....

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

In Option E, a student with an IQ of 150 doesn't belong to the group of students who are over 150. So the score of 150 is within the range of students who have an IQ score of above 120. According to the argument, it says that MOST students get accepted. This also means that not ALL of them do get accepted. So in Option E, it's wrong to say that if the student is not in an Ivy-league school then it means that he never applied because it is possible that the student did apply, but he was among the remaining few students who didn't get accepted.

I also chose C as my answer.

I fell for the contrapositive trap and chose B.

The stimulus says :

Everyone who has graduated from TopNotch High School has an intelligence quotient (IQ) of over 120.

=> G from TPNH ->IQ>120

!IQ>120 -> !G from TPNH

I too faced this question in MGMAT..It was such a pain in butt..fortunately I got it right..

I was stuck between "B" & "C" & chose "C" over "B" due to strong massage given via choice "B"

Yes, I've never seen such questions either in OG or in GMAT prep/actual GMAT. Infact , I don't take my MGMAT CAT scores seriously especially in the Verbal section of MGMAT..The questions are either 'off' or 'easy'..I personally love the MGMAT books, and I own all of them but their CATs disappointed me
