If x and y are positive, is 4x > 3y? (1) x > y - x (2) x/y < 1 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.
感觉(2)直接可以判定y>x,所以题中4x>3y 是否定的,为什么答案是E不是B呢?? |
