Answer 2

Answer:

Hello

I think the total number of pages that were torn out is 5.

Explanation:

As the page starts with odd number .... so following pair we get...

1,2 lies on a single page....similarly 7&8 lies on a single page... therefore we count it as 1.

Now,again we have 99&100 as a pair .... so from this we get the second page ....now page number 101 is also torn out...that contributes to 3 page... In the same way 221&222 are pair and lies in a single page which contributes to 4th page and the last is 223&224 here this pair lies in a single page...Hence ,we conclude that total number of pages that were torn out is equal to 5....
