The pages in nisha s book are numbered from 1.she found that total number of 501 digids are used to write all the page numbers. for example 2 digids for page number 23 and 3 digids for page number 101.how manny pages does the book have?

The number of pages in the book is 203.

Numbers 1 to 9 have 1 digit. This means that 9 pages in the book would have 1 digit. Numbers 10 to 99 have 9 digits. This means that 90 pages in the book would have 18 (9o x 2) digits. Numbers 100 to 199 have 300 (100 x 3) digits. This means that 100 pages in the book would have 3 digits.

Total digits left = 501 - (180 + 9 + 300)

= 501 - 489

= 12

Number of pages left = 12 / 3 = 4

Total number of pages in the book = 9 + 90 + 100 + 4 = 203 pages

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
