If 'x' is a positive integer exactly divisible by 6 or 15 but not divisible by 12.What could possibly be the value of 'x' ?	Choose the most appropriate option:
A) 120
B) 60
C) 36
D) 90
E) 54
120 and 60 are both divisible by 6 and 15 but also by 12. so they are not the right answer.   36 and 54 are both clearly not divisible by 15(not correct)   90 is both divisible by 6 and 15 but not by 12.   answer : (90) 90
<result>D</result>
