(2) x=5 Statement 1 says that the product of v and w is 0, hence v or w (or both) = 0 Sufficient because if any of term in a multiplication equals 0 the product of the multiplication will be 0 Statement 2 says that x is 5 Insufficient because it does not say anything about v or w. I would be sufficient if x=0 Answer A

1. It states that vw=0 , if x=infinity then we cannot determine the product value as it becomes 0*(1/0) so 0/0>>cant be determined. insufficient 2. x=5; but we dont know the values of v and w; insufficient 1+2>> Suffcient since x value is finite. Hence Ans C .... I am not sure how the OA is A because we never know what value x can take.

I am not sure how the OA is A because we never know what value x can take. Infinity is not a number

how can we determine if x is 8 or 10 or 10000?
