Answer should be E
x^2-x>0 => x(x-1)>0 => x<0 or x>1
Insufficient to tell if x<0
|x|>1 => x>1 or x<-1
Insufficient to tell if x<0
Together as well both the statements give us the result x<-1 or x>1. Insufficient

1. x(x-1)>0 => x>1 or x>0 (when both positive - No) & x<0 or x<1 (May or maynot be ) - Not sufficient
2.|x|>1 => x>1(no) & x<-1(yes) - Not sufficient
1&2 :
x<-1 : Yes ! - satisfies 1 & 2.
X>1 : No! - also satisfies 1&2.
Not suffficient.
