an integer > 1 that is not prime is called composite. If the 2 digit integer n is greater than 20, is n composite?

1. the ten digits of n is a factor of the units digit of n
2. the ten digit of n is 2.

A?

From 1. 99 / 99 / 33 / 22 /66 etc.... meets the rule, the tens digit 9 is a factor of the units digit 9? But we cannot consider 13, since the integer is greater than 20. SUFF

From 2. n could be 24 (composite) or 23 (prime) INSUFF
