Hi guyz....Anyone on the answer to the following Question?

I solved it straight forward to get the Answer as A which is wrong.

Please help !

My Approach...

[9]*[6] = 3*9*0.5*6 =81
{since 9 is odd [9]=(3*9) &
since 6 is even [6]=(0.5*6)}


Where am i going wrong??? :?:

Fine!

[9]*[6]

= (3*9) * (6/2)

= 81

Now, choiceA: [81] = 243
choiceB: [54]= 27
choiceC: [36]= 18
choiceD: [27]= 81
choiceE: [18]= 9

so given expression = 81 , choiceD
