The remainder when m+n is divided by 12 is 8, and the remainder when m-n is divided by 12 is 6. If m > n, then what is the remainder when mn divided by 6? A. 4 B. 1 C. 3 D. 2
Read Solution (Total 1)
-
- Assume that a is the remainder when m is divided by 12 and b is the remainder when n is divided by 12
then a + b = 8 and a-b = 6
or a = (8+6)/2 = 7 and b = 1
When mn is divided by 6, the remainder will be the remainder of (7*1)/6 which is 1
