Yes, everything you say is correct - one of S or T is positive, the other negative. And yes, it can be true, as you point out, that S+T = 0. Still, it might be that S+T is not zero; for example, S could be 4 and T could be -3. Since we can get two different answers ('yes' and 'no') to the question asked, the Statement is insufficient.chetanojha wrote:Hi Vemuri,
I still didn't understand why statement 2 in insufficient. If 0 is between S and T, and if S&T are two different numbers, does it not mean that either S or T is negative and other is positive?
e.g. S=-5 and T=5 hence 0 is middle of the two numbers and S+T=0?

Yes, you are. Your second interpretation of the statement is the correct one. If 0 is between S and T, that does not necessarily mean that 0 is halfway between S and T. For example, 0 is certainly between -3 and 14.chetanojha wrote:Hi Ian,
Statement 2: 0 is between S and T. Does this mean 0 is in middle of S&T or 0 is anywhere between S&T? in later case, what you have said would be correct answer. Am I getting it right?
