Question

Drashti read 2/3 of a book and find that the read number of pages is 90 more than the number of unread pages find the total number of pages in the book​

Answer 1

Answer:

Step-by-step explanation:

let the no.of  pages is x

no.of read pages is 2x/3

then the read pages no. is 2x/3-90

A.T.Q.  2x/3 +2x/3 -90=x

        =>4x/3-90=x

        =>4x/3  -x=90

        =>x/3=90

        =>x=90*3=270

so total no.of pages is  270

Answer 2

Pages read by Drashti = 2/3

Pages which are not read by her = 1 - 2/3

= (3 - 2)/3 = 1/3

Let us assume that book contains X pages.

Pages which are not read = 1X/3

A.T.Q.

2X/3 - 1X/3 = 90

(2X - 1X)/3 = 90

1X/3 = 90

1X = 90*3

X = 270

Total number of Pages in the book = 270
