Question

Sandeep reads 3/5 of a book. He finds that there are still 80 pages left to be read. What is the total number of pages in the book? *

Answer 1

Answer:

200

Step-by-step explanation:

It is being given that,

Sandeep reads 3/5 of a book.

No. of pages left to read = 80

Let the total number of pages = x

Therefore, We have the relation,

[ 3/5 of y = y -80 ]

3/5 of y = y -80

3/5 x y = y -80

3y/5 = y -80

3y/5 - y = -80

= 3y - 5y /5 = -80

= -2y/5 = 80

= -2y = -80 x 5

= -/2y = -/400

y = 400/200 = y = 200

Total pages = 200

The Total pages in the book are 200
