blind shot C?

S2 is true for both:
A = -4, B = -2
A = 0, B = 0

S1: rules out second possibility

ans: -4

yb · Answer

B.

1) Insuff, b/c we don't know anything about C1

2) SUFF, b/c we can determine A is -4, and B is -2

yb · Answer

I didn't consider the second possibility where A and B could both be 0. I change my answer to C. Good work duttsit

GMATT73 · Answer

That is definately a higher level of thinking Duttsit! Even if B were worded: The distance from A to 0 is 100 times the distance from B to 0, statement two is always insufficient.

Convinced that it`s (C)
