Letâ€™s assume that the class has n students. Thus, he has collected 200 x (2/5)n = 80n dollars. Since this represents 1/4 of the required fund, thus he still needs 3/4 of the required fund, i.e., 3 x 80n = 240n dollars. Since the the remaining number of students in the class is (3/5)n, then the per- person contribution from these remaining students is:

240n/[(3/5)n] = 240 x 5/3 = 400 dollars

OA D Let's say Jason has 5 classmates. If he receives$200 from 2/5 of them, or from two classmates, he'll have 2*200 = $400. If$400 is 1/4 of what he needs, then he requires a total of 4*400 = 1600, leaving him 1200 short of his goal.

So, from the remaining 3 students, Jason needs to raise 1200, or 1200/3 = $400 each. The answer is D I interpreted this question differently. Receiving$200 from 2/5 of them implies to me that the total supplied by 2/5 of the class is $200, not that each provides$200.

In which case $800 was the bogey,$600 remaining among 3 members requiring $200 each. Not unreasonable - the question could have been worded more precisely to avoid any ambiguity. For my interpretation, it probably should have read "Jason received$200 each..." For your interpretation, "Jason received $200 total..." _________________ Veritas Prep | GMAT Instructor Veritas Prep Reviews Save$100 off any live Veritas Prep GMAT Course
