Say I've decided that A, B are out, each is not sufficient.

Combining,
\(\frac{n}{m} < 1 means \frac{m}{n}> 1\)
So,
\(\frac{(m-n)}{n} >0\)

If it's given that n > 0 (Combining B)
(m-n)> 0. So, m > n

So I implied
Am I missing anything?

Is m > n?

(1) n /m < 1
(2) n > 0

Kudos for a correct solution.

1: if m > 0, n < m. If m < 0, n > m. So insufficient.
2: Insufficient, tells nothing about m.

Together: insufficient. m can still be negative or positive. For example, n = 4, m = 8, m > n. But if n = 4, m = -8, n/m < 1 and n > m. Answer is E.

\(\frac{n}{m} < 1 means \frac{m}{n}> 1\)
That assumes that m and n have the same sign (since you are multiplying both sides by m/n). If they have opposite signs (so m/n < 0), you have to change the inequality.

You can't take reciprocal if you don't know the sign. If m = 2 and n = 1, then \(\frac{1}{2}<1\), and \(\frac{2}{1}> 1\), but if m=-2 and n = 1, then \(\frac{1}{-2} < 1\), and \(\frac{-2}{1} < 1\).
Sign changes only if both are either negative or positive.

Is m > n?

(1) n /m < 1
(2) n > 0

Kudos for a correct solution.

MANHATTAN GMAT OFFICIAL SOLUTION:

(1) INSUFFICIENT. It is tempting to cross multiply to get n < m. However, we don't know whether m is positive, so we don't know whether to flip the sign.

(2) INSUFFICIENT. This statement tells us nothing about m.

(1) & (2) INSUFFICIENT. The fact that n is positive does not tell us whether m is positive. For example, it is possible than n = 2 and m = –1. It is also possible that n = 2 and m = 3. Either of these scenarios would fit Statements (1) and (2) but yield different answers to the question.

The correct answer is E.
