Question

If n is divisible by 2 but not by 3, then what is the remainder when N is divided by 6

Answer 1

let b be 6
then r=0,1,2,3,4,5
then a=6q,6q+1,6q+2,6q+3,6q+4,6q+5
according to given condition
it must be divisible by 2 but not by 3
6q+2 and 6q+4 satisfies the condition.
Hence the remainder may be
2,and 4 .
