Question: Is xy < 0?
For xy<0, a and y must have opposite signs i.e. x must be negative and y must be positive as per number line and 0 must fall somewhere between x and y
Statement 1: Zero is to the left of y on the number line above
i.e. y > 0
but x may be positive as well as negative hence
NOT SUFFICIENT
Statement 2: xy and yz have opposite signs
Case 1: x = -ve, y = -ve and z = +ve i.e. xy > 0
Case 2: x = -ve, y = +ve and z = +ve i.e. xy < 0
NOT SUFFICIENT
Combinig the statements
We are left with only Case 2: x = -ve, y = +ve and z = +ve i.e. xy < 0
SUFFICIENT
Answer: Option C
