Question: is |x| > |y| ?
Statement 1: x = -2y
since, it's given that xy≠0, |x| = |-2y| and |-2y| is greater than |y| hence
SUFFICIENT
Statement 2: x = y^4
|x| = |y^4| but
i) |y^4| may be smaller than |y| if -1 < y < 1
ii) |y^4| may be greater than |y| if |y| > 1 hence
NOT SUFFICIENT
Answer: Option A
