Do you mean to say in stmt 2 that "there are 6 numbers in S"?
If yes, then it would be E.
1) product of all numbers = -1200
It can be framed in many cases, to name a few
i. -1200 * 1*1*1*1*1 = -1200 (More positive numbers than negative numbers)
ii. It can be a series of negatives and few positives. Can't think of numbers at the moment.
Also there can be many numbers, say 100 or 1000
Insufficient
2) Clearly insufficient. You can form any number of positives and negatives.
Together, again insufficient. Although we know that there are 6 numbers in the set, we can come up with any number of positives and negatives.
Hence E.
