If N = 1000x + 100y + 10z, where x, y, and z are different positive integers less than 4, the remainder when N is divided by 9 is
(A) 2
(B) 4
(C) 6
(D) 8
(E) 9
The OA is C.
How could I find the remainder? Can I say that N is a the 4 digit number "xyz0" ? Or what are the calculus needed to solve this PS question?
