(2) The sum of the digits in n is 10.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
（1）30=1×2×3×5，所以符合条件得可能大于550，比如561，651等，也可能小于550，insuffient
（2)insufficient
（1)(2)则符合题意的数组为3,2,5，可组成的最大数为532＜550，可比较。
