If x is an even integer, which of the following must be an odd integer?	Choose the correct choice from the following answers:
A) 3x/2	B) [3x/2] + 1	C) 3x^2	D) [3x^2]/2	E) [3x^2/2] + 1
x is E (even) and therefore x^2 is E.   3x^2 is E, as it is O*E   Therefore, 3x^2/2 will be E. (since x is integer, x^2 &gt; 2)   If you add 1 to an E number, you will always get odd.   Hence, [3x^2/2] + 1 is the answer.
