I. m ≠ 0

II. 6m = 9n

Option A:

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.

Option B:

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.

Option C:

BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.

EACH statement ALONE is sufficient to answer the question asked.

Option E:

Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

Question is 2m=3n ?

Statement I is insufficient:

m≠0 –> clearly insufficient as no info about n.

Statement II is sufficient:

6m=9n –> reduce by 3: 2m=3n, so this statement directly answers the question (so here it doesn’t matter whether m and n are integers). Sufficient.
