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

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

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

l        EACH statement ALONE is sufficient

l        Statements (1) and (2) TOGETHER are NOT sufficient

AnswerA

我觉得应该选C

我觉得应该选C

第一个条件直接告诉你答案了，第二个单独没法推断

我觉得是C

从1可以得出 MAY1 的balance. 结合2的增长率可得M30的

是不是答案有问题？

请高人赐教！

checking account 增长了12％，可得出MAY 1的值，再用2)的条件，得出MAY30 的值。答案是C。
