When the integer k is divided by 12, the remainder is 3. Which of the following, when divided by 12, will have a remainder of 6?
I. 2k
II. 6k
III. 4k + 6
(A) I only
(B) II only
(C) III only
(D) I and II only
(E) I, II, and III
How to attack such problems?
The way I try to resolve is: q- quotient, R-remainder
k = 12q + R = 12q + 3 ..........(1)
and then I get lost

II. 6k
