Question

X is a number formed by the first 101 digits of the number n which is formed by writing 100 natural numbers one after the another as follows 1234567891011... Find remainder when x is divided by 4

Answer 1

Answer: 3

Step-by-step explanation:

First 9 digits will be 123456789

Then next 101-9=92 digits will be the numbers from 1011213.....till 92/2+9=55

So the last two digits will be 55.

So the remainder obtained by the given number and the remainder obtained by 55 will be same and that is 3
