6, or 15, then N is a factor of 30. However, for all other multiples of 3 less than 30, N is

not a factor of 30. Thus, statement (2) alone is insufficient to answer the question.

Considering the two statements together narrows down the possible values of N to

three numbers: 3, 6, and 12. Of these three numbers, only two—3 and 6—are factors of
