For all positive integers m, @m = 3m when m is odd and @m = m/2 when m is even. Which of the following is equivalent to @9 * @6?
A. 81
B. 54
C. 36
D. 27
E. 18
It looks like an easy one, but I cant believe that the GMATPrep test has my answer as incorrect. I answered choice A i.e. 81. Is this answer really incorrect? How? It needs a simple calculation
@9 * @6 = 3*9 * 6/2 = 27*3 = 81
