Q32:

If m and v are integers, what is the value of m + v?

(1) mv = 6

(2) (m + v)2 = 25

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

这题答案是B吗？第二个条件可以得出两个答案，这算是充分条件吗？

应该是E啊,你的答案好像不对啊.

我觉得是b阿，因为通过条件2，m+v=12.5,非整数，也就说明m+v没有整数解，已经充分的回答了问题
