When m is divided by 6, the remainder is 3 and when n is divided by 12, the remainder is 9, where m and n are positive integers. Which of the following could be the value of m+n?

I. 72
II. 108
III. 180

(A) I only
(B) II only
(C) III only
(D) I and II
(E) I, II, and III

m is of the form 6k+3 so 3,9,18,27,36,45,54.
n is of the form 12j+9 so 9,21,42,63,84,105,126.
I. 72 - 63+9
II. 108 - 63+45
III. 180 - 126+54

Hence E
