Both statements are satisfied if m=-1 and n=0, in which case m<n.
Since the answer to the question stem is YES in the first case but NO in the second case, the two statements combined are INSUFFICIENT.
The correct answer is E.

Statement 1: |m| > |n|amontobin wrote:Is m>n?
(1) |m| > |n|
(2) m^2>n^2
=> m > n if m and n are positive numbers. For example, say m = 2 and n = 1. The answer is Yes.
However, m < n if m and n are negative numbers. For example, say m = -2 and n = -1. The answer is No. Not sufficient.
Statement 2: m^2>n^2
=> |m| > |n|.
It's the same statement as is Statement 1. Not sufficient.
Even combining them will not help as both the statement are in fact the same.
The correct answer: E
