Statement 1 : 9y - 6x > 0 i.e. 3x > 2y i.e. x > 0.66y i,e. x may be greater than y or less than y hence NOT SUFFICIENT Statement 2 : x*y>0 i.e. x and y have same signs and are non zero but the comparison between values is still absent hence NOT SUFFICIENT COmbining the statements x*y > 0 and x > (2/3)y Case 1: y = 3 and x = 2.5 i.e x < y Case 2: y = 3 and x = 4 i.e x > y NOT SUFFICIENT Answer: Option E
