Is the three-digit number n less than 550 ?
(1) The product of the digits in n is 30.
(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.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
①满足的两组数:3,2,5; 5,6,1。但651比550大,156比550小,因此无法比较大小。故,①单独不成立
②如721>550,127<550,无法比较。故,②单独不成立。
若①②同时满足,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。
