If QR = 3(Q+ 1) + R and Q and R are integers,Q could be any of the following values EXCEPT:  Choose the correct choice from the following options:	A) 2	B) 3	C) 12	D) 4	E) 7
QR = 3(Q + 1) + R   QR - R = 3(Q + 1)   R = 3(Q + 1)/(Q-1)   R won't be an integer only if Q = 12 (from the options).   Answer: 12
