Question

The whole number are written across a piece of paper in order. There is room for 100 digits on each line and there are no spaces between each digit. What are the last 5 digits on the second line?

0123456789101112.......

Answer 1

single digit numbers:
10 of them
spaces needed: 10

double digit numbers:
90 of them
spaces needed 180

so the numbers from 0 - 99 require 190 spaces.
Starting in position 191 , we start writing 3 digits numbers.
So the remaining last 10 places of the second row would be
1001011021
making the last 5 digits of the second row
11021

Answer 2

you need 10 single digits (0123456...)
10 spaces

90 double digits
180 spaces

180+10=190
in 191, there are 3 digit #s
so it would be 100 101 102 1, or 1001011021, so the last 5 digits are 11021
