You need to pay attention to what the answer is saying.. its not asking you to find 9x3x3 which is 81 .

You need to find, the reverse i.e.

|9|x|6| = 3x9 x 6/2 = 27 x3 = 81

Now 81 = 3 x 27 = |27| (27 is odd => 3m)

Therefore Answer is : D. |27|

Just one of the type of questions where the GMAT makes us pick the one you calculate first.

Hi,
it is a simple gmatprep trick:

|9|*|6|=81

|81|=243 - not equal

|27|=27*3=81 - equal

Simple. Remeber the answer choices are also in boxes

Hence [27] = 27*3 = 81
and [9] * [6] = 9*3 * 6/2 = 27*3 = 81

This is one where I still don't understand

Isn't the number in the box the final answer?
So for example 9 in the box makes m-3?
