Text solutionVerified

No. of digits in 1-digit page no.

\Rightarrow 1 \times 9 = 9

No. of digits in 2-digit page no.

\Rightarrow 2 \times 90 = 180

No. of digits in 3-digit page no.

\Rightarrow 3 \times 900 = 2700

No. of digits in 4-digit page no.

\Rightarrow 300

∴

No. of pages with 4- digit page no.

= (300/4) = 75

Hence, total no. of pages in the book

= (999 + 75) = 1074
