In N is a positive integer less than 200, and 27N/60 is an integer, then N has how many different positive prime factors? Choose the correct choice from the following.
A) 2	B) 3	C) 5	D) 6	E) 8
(A).   27n/60 must be an integer. =&gt; 9n/20 must be an integer. Hence n must be a multiple of 2*5.   =&gt; n has 2 different prime integers.
