Question

When a number P is divided by 4 it leaves remainder 3. If twice of the number P is divided by the same divisor 4, then what will be the remainder?

• A. 0
• B. 1
• C. 2
• D. 6

Answer 1

Answer: (C)

2

Given, $P=4x+3$

$2P/4=2\times (4x+3)=8x+6$

Here, $6$ is the remainder.

But we can further divide the remainder as $4+2$,

So, $2$ is the remainder for $2P/4$.
