Suppose there are 100 students in the firts year class. 68 of them will graduate in the fourth year and 34 of them will be in the leadership program. In the May 2003 graduating class, only 30% of the students are in the leadership program. i,e., the number of students now in the graduating year (fourth year) is (34 / 30)*100 = 110. So there are more students in the graduating class of May 2003 than it had at the beginning. Since students who do not graduate within four years are disqualified from participation in Leadership Program, this is the only possibility.

I go for A.

B is out since if there are any students who does not graduate within four years will be disqualified from the leadership program. So participation in the leadership program does not in anyway contribute to graduation.

I go with B..

Lijo - I did not understand the explaination you gave for ruling out B. Could you please re-phrase it ?

One more for A. Same reasoning as lijo

rthothad · Answer

Let me give it a shot

Students are members of LeaderShip program only after they graduate within four years, so this is the effect of graduating within four years and not the cause

pb_india · Answer

Its a clear D, what are we debating about?

pb_india · Answer

Sorry about premature reply.
THinking hard, seems like A to me.

30% of 11 = 113

So entering = 100, in May 2003 there were 13 students more.

Clearly A.

Dear Raja,
The question states that "Exactly half of those graduating students  are members  of Leadership Program. Students who do not graduate within four years are  disqualified  from participation in Leadership Program"
It is never said that they are the  only members  in the leadership program. There may be other students too, the number of whom is uncertain. So it can not be  clearly and absolutely  the case that they have a higher likelyhood of graduating.

These questions dont appear to be GMATtty?? What is the source of this question? This appears to be more an LSAT type of question, no? 

Should we be prepping for questions like this?

lijo · Answer

OE please. D is a straight forward answer, but the use of  Exactly 
  still confuses me.

wunderbar03 · Answer

B is my choice. Waiting for OA explanation.
