A combined total of 55 lightbulbs are stored in two boxes; of these, a total of 7 are broken. If there are exactly 2 broken bulbs in the first box, what is the number of bulbs in the second box that are not broken?
(1) In the first box, the number of bulbs that are not broken is 15 times the number of broken bulbs.
(2) The total number of bulbs in the first box is 9 more than the total number of bulbs in the second box.
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.

哦哦看错了，答案是D
这道题为何不是D？
(2) The total number of bulbs in the first box is 9 more than the total number of bulbs in the second box.
第一个盒子的灯泡总数 是 9 + 第二个盒子的灯泡数，这明显可以求的呀？
如果按照B的来讲，分拆10份，比例1：9，那么会导致的分配比例为为5.5：49.5，不是整数的电灯泡，不知道是否符合真是逻辑？
