Answer 1

Answer:

525 Pages

Step-by-step explanation:

A printer number the pages of blook starting with 1 and uses 3089 digits in all. How many pages does book have

Single Digit number  1 to 9       Digits used - 9

Two digits numbers 10 to 99   Digits used  = 90*2 = 180

Three digit number 100 to 999  Digits used  900*3 = 2700

Remaining digits = 3089 - 2700 - 180 - 9 =  200

four digits number = 200/4 = 50

Four digit numbers 1000 to 1049  

First Page number = 1

Last Page number = 1049

Number of pages would be half as each page has two sides

Number of pages = 1049/2  = 524.5

(.5 implies that last page foes not have back side printed)

=> 525 Pages

book have 525 Pages
