Great and easy approach palvarez !!palvarez wrote:Rephrase it
Is a^2 - b^2 > 0
or (a+b)(a-b) > 0
1. a+b < 0, insufficient, since we need to know if a - b > 0
2. a < 0, insufficient.
Both insufficient, since we can't say b < 0. However, if (1) would have been b < a, the answer wud be C.
You should take a break buddybrick2009 wrote:hi abdulla.. u post the OA as A and say palvarez is right.. with his ans as C?
what is the OA?
rephrase: |a|-|b| <0
a.) b < -a --- insuff
b.) a<0 -infus
only value possible for a = -ve
..by substituting.. ans should be E and not C
Check my answer again ... and read the last sentence in palvarez's post again...
