Question

When N is divided by 4, the remainder is 3. What is the remainder when 2N is divided by 4?

• A. 2
• B. 3
• C. 4
• D. 8

Answer 1

The correct option is A 2

According to the question, $n÷4=q+3$
Where, q is quotient
$n=4q+3$
$\therefore 2n=2(4q+3)$
$\Rightarrow 2n=8q+6\Rightarrow 8q+4+2$
$\Rightarrow \frac{8q+4+2}{4}$
$\therefore reminder=2$
