Qᴜᴇsᴛɪᴏɴ :- Totally 360 digits one used in a book. If so,how many pages are there in the book ?
Sᴏʟᴜᴛɪᴏɴ :-
Lets First understand the Question . Meaning of Question is when we look at the page numbers, and count up the total number of times any digit appears, how many pages will it have if the total is 360...
Now,
First assume the first page is labeled page 1 and a page constitutes one side of the page.
→ Single-digit pages is 9*1 = 9 Digits.
→ Double-digit is (99 - 9)*2 = 180 Digits.
Now , Rest are Three - Digits.
So,
→ Three - Digits = 360 - (9 + 180) = 171 Digits.
Therefore,
→ Pages with 171 Digits = (171/3) = 57 Pages.
Hence,
→ Total Pages in The Book Are = 9 + 90 + 57 = 156 (Ans.)
∴ Their are 156 Pages in The Book.
