Answer 2

Answer:

Step-by-step explanation:

Given data-

N÷4 GIVES REMAINDER 3

For this

Basically, N is of the form 4k+3 where k is an integer!

(This is because, it leaves a remainder 3 when divided by 4)

Now, put k=0,1,2,3…..

AND BOOOOOOOOOOOOM! There you are!

k=0 => 3 => Ones digit is 3,

k=1 => 7 => Ones digit is 7,

k=2 => 11 => Ones digit is 1,

k=3 => 15 => Ones digit is 5,

k=4 => 19 => Ones digit is 9,

k=5 => 23 => Ones digit is 3.

We see that the pattern repeats! So, the ones digit is either 3,7,1,5,9.

But the Answer is 7 because 7÷4 GIVES REMAINDER 3
