Question

when a number'n' is divided by 4 we get the remainder 3 then what is the remainder if 2n is divided by4​

Answer 1

Answer:

Answer is 2

Step-by-step explanation:

Suppose the number be n

So out of this the part which was divisible by 4 be x and the remaining non divisible is 3 (given in the question)

Consider the following example to get what I wrote in above line

Suppose the n = 15

Out of this n = 12 + 3

Now the X = 12 and the non divisible part is 3

Similarly for the 2n the non divisible part will 3 two times and out of 6 = 4+2

4 is divisible by 4 and the remaining is 2 i.e is remainder and your answer!
