m=3m,when m is odd
m=1/2m,when m is even
9*6
m=9 is odd,m=27
m=6 is even,m=3
27*3=81
Pick A

I remember this question.There must be one symbol like []
[m]=3m,when m is odd
[m]=1/2m,when m is even
[9]=27
[6]=3
[9]*[6]=81
81 is expressed by[27] (since 27 is odd [27]=81)
Pick D
This is the question in GMATPREP ?rt?

[m]=1/2m,when m is even

I didn't get the last step i.e how 81 is expressed as 27.selango wrote:I remember this question.There must be one symbol like []

Because the answer options are expressed as symbol[]
[9]*[6]=81
81 is odd..How to express 81 in symbol [] form?
[m]=3m,when m is odd
[m]=81
[m]=3*27
-->m=27
[27]
Hope this clarify..

Friends can it be this way ?
9*6 =54
so m is even and therefore m/2.
therefore 54/2= 27
9*6 =54
so m is even and therefore m/2.
therefore 54/2= 27
Thanks and regards,

I can understand you not winning,but i will not forgive you for not trying.

This is how i solved it. m can be either odd or even but not both at the same time.
Lets take m=odd. So in 9 x 6, m is 9. Therefore 9x3=27 and 27x6=162. Since 162 is not a given answer, m cannot be odd and therefore must be even (m is a positive integer).
If m is even, then in 9x6, m is 6. so 1/2 x 6 = 3 and 9 x 3 = 27. 27 also exist in our answer options.
Therefore, answer is 27 or D.
