At a certain college ther are twice as many English majors

For all positive integers m, m*=3m when m is odd and m*= m/2 when m is even. Which of the following is equivlant to 9*x6*?
A) 81* B) 54* C) 36* D) 27* E) 18*

Now 9* = 3m = 3 * 3
& 6* = m/2 = 12/2
9*6* = 3x3x12/2 = 54 = 27* (For even number - 27* = 54/2)
