Answer 2

Step-by-step explanation:

Given:-

drishti read 2/3 of a book and found that the read number of pages is 90 more than the number of unread pages.

To find:-

find the total number of pages in the book.

Solution:-

Let the total no. of pages in a book be X

Read pages by Dristhti =2/3 of a book

=>(2/3)×X

=>2X/3 pages

Remaining pages =X-2X/3

=>(3X-2X)/3

=>X/3

But given that

the read number of pages is 90 more than the number of unread pages

=>2X/3=X/3+90

= 2X/3-X/3=90

=>(2X-X)/3=90

=>X/3=90

=>X=3×90

=>X=270

Solution:-

Total number of pages in a book =270
