gmataspirenew Posted November 13, 2008 Share Posted November 13, 2008 If v and W are different integers, does v =0 1) vw = v*v 2) w = 2 Guess the problem is quite simple. But I wanted to confirm that if V is an integer then it can be 0? (In GMAT terminology) Quote Link to comment Share on other sites More sharing options...
e.cartman Posted November 13, 2008 Share Posted November 13, 2008 Yes, 0 is an integer. Ans is E because together v=0 or 2 is possible. Quote Link to comment Share on other sites More sharing options...
supersuj Posted November 13, 2008 Share Posted November 13, 2008 IMO, A statement 1--> v^2-vw=0 v(v-w)=0 v=0 or v=w Since v and w are different integers, v cannot equal w, so v must be 0...SUFFICIENT statement 2--> no info about v...INSUFFICIENT YES, 0 is very much an integer Quote Link to comment Share on other sites More sharing options...

genius_in_the_gene Posted November 13, 2008 Share Posted November 13, 2008 1) vw = v*v 2) w = 2 1)vw = v*v Either v=0 or v=w Now since w and v are different, v!=w 2)w=2 not suff ANS A Quote Link to comment Share on other sites More sharing options...
