n is a whole number which when divided by 4 gives 3 as remainder. What will be the remainder when 2n is divided by 4 ?
Answer: Option
Explanation:
Let n = 4q + 3. Then 2n = 8q + 6 = 4(2q + 1 ) + 2.
Thus, when 2n is divided by 4, the remainder is 2.

If n=19 then 2n = 38.
2n/4=38/4 (here remainder is 2) =19/2 (here remainder is 1).
Why does remainder change for the same fraction? Please explain me.
