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?
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
making the last 5 digits of the second row
