for 2) b+c+d=300.....(1) a =>a+c+d (1)+(2) a+b+2(c+d) 200+2(c+d) 2(c+d) c+d c+d

when a.b=0 and b=1 L.S.=0 R.S.=a+1-a=1 LSRS, impossible. b cannot be 1.

1)a^2>=0 2)b0 =>b^2>0 1)+2) a^2+b^2>0

589. Please reserve 700 for me and for my GMAT!

Interesting! See the second post from Agent_777.

Vreddy, Just want to share some idea. it seems A is sufficient. I will do it by tomorrow if possible.:)

Zorrillo, That is a good question. I am still comtemplating on a date. I am mulling to take both GRE and GMAT. Do you have any GRE info to share? I would appreciate that.

when b >=8 |b+8|+|b-2| = 2b+6, this is always greater than 10. Sufficient So, answer is B.

Vreddy, You mean A? Sufficient. A is the answer?

Markus, you are welcome.:)

Hi Markus, Locate MATHREV1.HLP, MATHREV2.HLP, MATHREV3.HLP and MATHREV4.HLP from c:etsppgmatppgmat first and then use some tools such as "Windows HLP To RTF2.6" to convert windows help file to one common document file.
