if 2/3 of leftover = $32
1/3 of leftover = $16
$16+$4 = $20.
Thank you

S (total distance) = v (speed) x t (time) v1, t1, S1: speed, time and distance of first half of distance v2, t2, S2: speed, time and distance of second half of distance (1), (2) each is not sufficient. From (2)S1= S2 => v1 x t1 = v2 x t2. As v1 = 2v2 => t2 = 2t1 We have t1+t2 = t = 4 hrs (the questi...

Hi Ian In statement 1, why could you point out only 1 case a = b = +/- 1. IMO, from a^2 = b^2 we may have a = b = +/-1 or 2 or 3 or ....? Am I misunderstanding something? Thanks a lot #4-9 If a does not equal to zero, is 1/a > a/(b^4 +3)? (1) a^2=b^2 (2) a^2=b^4 Thanks! Spoiler: The correct answer i...

Any time we place 2 points, one must come first. Let's say A. So, now we just care about the probability that B is placed to make AB at least 2. when Chord AB = 2, we have AB=OA=OB=2, so AOB = 60 degree (O is a center). The point is that we can place B at the RIGHT SIDE or the LEFT SIDE of A so &quo...

Thanks guys Anyway, D is a better choice because it directly relates to the conclusion made from the question while C just focuses on the manufacturer's purpose of demanding pharmaceutical label for its products.

thanks for your reply.

I got 610 on GMATPrep and 700 on Barron Test. In my opinion, Barron Test seems to be easier and GMAT prep seems to be tougher than OG questions.
