Greetings all. I'm beginning my studies for the GMAT, and am working through the Manhattan GMAT study guides.
One of the problem sets has a question that reads:
If 6 is not a factor of d, is 12d divisible by 6?
a) Yes
b) No
c) Cannot Be Determined
Manhattan records the answer as Yes, but I do not see why it is not CBD.
My reasoning: though 12 is divisible by 6, the problem does not state d to be an integer. Is there a term of art that I am missing that would imply this scenario?
Thanks.

For problems #1-11, use one or more prime boxes, if appropriate, to answer each question. YES, NO, or CANNOT BE DETERMINED. If your answer is CANNOT BE DETERMINED, use two numerical examples to show how the problem could go either way. All variables in problems #1 through #11 are assumed to be INTEGERS unless otherwise indicated.
