81 is the result of[9]*[6]
But the answer choices all have the [ ] which u have missed. If 81 is the result
then the answer needs to be [27]
27 is odd therefore 3m = 3*27 = 81 which is result we obtained
Hope this helps!

Really easy but tricky question. I also fell in the trap, and got it in the review only.

[] is just a reference in this particular Qn. It doesnt signify anything else but what is specified in the question.kschmudde wrote:Sorry for my ignorance, but what does the [ ] signofy? That it is a result?
i think, the answer should be 81, not 27. pls correct me if i m wrong.
sol:
if M is odd (ie M=9)
[M] = 3 * M
=>[9] = 3 * 9 = 27 // Result 1
if [M] is even (ie M=6)
[M] = 1/2 * M
=>[6] = 1/2 * 6 = 3 // Result 2
From Result 1 & 2
[9] * [6] = 27 * 3 = 81 // Final Result
pls free to contact me if you have any other questions. thx.
