Thanks for the explanation Stuart!!!

So The takeaway of this problem is Pls recheck the solution to a DS question where the answers contain 0 in both answer choices. Combined, they can provide a solution and therefore can change the correct answer choice.

Hope this helps.

From 1 , the number is odd.
It can be 127 or 721, insuff.
from 2, the number < 700
it can still be 127 or 172
combining both,
odd and less than 700 is only 127.
Hence ans is C

1 will make up for 1 positive 0 will not be positive or negative (non positive and non negative) We will violating Exactly half of all elements of set S are positive Since there are 4 elements 2 need to be positive and in the example above only 1 (i.e. integer 1 is positive) Thanks a lot... Now i k...

Stuart,

Doesnt the set (-1,-1,0,1) saisfy both the conditions?
