Is x a negative number?
(1) x2 is a positive number.
(2) x · |y| is not a positive number.
OA is E, but shouldn't the answer be C
[spoiler]From (1) I can conclude that x cannot be 0, but x can be -ve or +ve number.
From (2)I can conclude that x.|y| is either 0 or -ve number.
for this to be possible either x should be 0 or -ve number as irrespective of the value of y ; |y| is going to be positive.
Combining (1) and (2) we can say that x cannot be 0 , so x has to be negative.
