Question

How many zeros will be required to number the pages of a book containing 1000 pages?

Answer 1

Answer:

Step-by-step explanation:

And then if, the pages 1–9 are not numbered as 01, 02, 03…09,

Then, the answer is 111.

Illustration:

The zeros required for 10,20,30,…90 series: 9

The zeros for the 100: 2

The zeros for 110,120,…190…210,220,…290…910,920….990: 9*9= 81

The zeros for 200,300,…900 series: 8*2= 16

The zeros for the 1000 finally: 3

which all totals to 111.
