What is the sum of a certain pair of consecutive odd integers?
(1) At least one of the integers is negative.
(2) At least one of the integers is positive.

IMO C
To know the sum, one number has to be negative and the other positive.

e.cartman · 2008 October 8th, 06:30 PM

Yeah C. -1+1=0.

bose · 2008 October 8th, 08:57 PM

yes c it is -1+1

Completely missed the question. Two numbers with different signs can't be consecutive odds except 1.0 is neither odd nor even. Agree with Bose and Cartman.

How this can be C...i went for E...
(1)-> at least one no is negative... => -1,1,3,5=> Sum=8
-3,-1,1,3=> Sum=0...Insufficient..
(2)-> at least one no is positive...=> -5,-3,-1,1=> sum=-8
-3,-1,1,3=>Sum = 0.. insufficient..

combine..
we still have above cases valid...so how can it b C...
@genius..pls explain..
