prep question

Post Mon Apr 23, 2007 12:49 am
Among a bunch of sweaters, 3/5 are pullovers and 1/4 are white. What portion of all the sweaters is not white pullovers?

(1) There are 60 sweaters in total
(2) 1/3 of the pullovers is white

Just by eyeballing I know its D, but just wondering how to solve it..

hmm ... i agree with prassana .. the answer is B and not D ... just a word of caution "eyeballing" culd prove fatal in DS ... there needs to be a concrete strategy to solve DS ...
