What was the amount of money donated to a certain charity?
(1) Of the amount donated, 40 percent came from corporate donations.
(2) Of the amount donated, $1.5 million came from noncorporate donations.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
题目分析：
（1）条件1给出了40%来自企业捐赠，不知道企业捐赠的数额，也无法计算捐赠总数。
（2）条件2说明150万美元来自非企业捐赠，仅条件2也无法确定企业捐赠的数额。
综合条件1和条件2，由条件1可知，60%来自非企业捐赠，又由条件2知道非企业捐赠为150万美元，所以，捐赠总数为150/0.6=250万美元。
因此，本题答案为（C），两个条件结合起来才能解题，任何单独一个均不行。
only include corp and nonecorp
