Question

Reemu read the 15th pages of a book. If she reads further 40 pages, she would
have read 710th pages of the book. How many pages are left to be read?

Answer 1

Let total pages be x

ATQ,

(x/5)+40=7x/10

(x+200)/5=7x/10

Cross multiply

10x+2000=35x

10x-35x=-2000

-25x=-2000

x=2000/25

x=80 pages

Therefore pages left= 3/10 of pages

=3*80/10=24 pages
