Answer 2

Given:

Numbers from 1 to 100

To Find:

How many times 1 has come in this interval

Solution:

To find the number of 1s from 1 to 100 let us divide this interval into subcategories to easily count down the number of 1s

• From 1 to 9 there is only 1
• From 10 to 19 there is 11 1s that is 10 11 12 13 14 15 16 17 18 19
• From 20 to 99 there is 8 1s that is 21 31 41 51 61 71 81 91
• Now the remaining is 100 that has only 1 1

SO counting down from 1 we have a total of (1+11+8+1)=21 ( it is preferred to sub categorise like this to have an easy imagination of counting down the numbers and you can further make your own interval counting for bigger intervals

Hence, the total number of times 1 is coming from 1 to 100 is 21.
