You have to divide your answer by 3 because it is talking about some equivalent, so the answer should be 81/3 i.e 27.

You are indeed missing something very important: in the GMATPrep question, the function symbol appears in all of the answer choices. I've amended the question to reflect its original intent.

Since #m# = 3m when m is odd, #9# = 3*9 = 27.
Since #m# = (1/2)m when m is even, #6# = (1/2)*6 = 3.
Thus, #9# * #6# = 27*3 = 81.

Answer choice D:
Since #m# = 3m when m is odd, #27# = 3*27 = 81.

The correct answer is D.

Thank you Mitch.

Can't believe I missed it.

Even though this question was one of the first few questions of my practice test and I was comparatively less pressured, I still missed the symbol in the answer choices. What is funny but important is that I was so sure that I did the math right but still selected the wrong choice.

I guess this is a classic example of predictable wrong choice given in the answer choices.

I have to be more attentive.

Thanks again.
