Question

Reemu read (1/5)th pages of a book. If she reads further 40 pages, she would have read (7/10)th pages of the book. How many pages are left to be read
​

Answer 1

Answer:

let the no of pages be x

then ; 1/5x +40 = 7/10x

7/10x -1/5x =40

35x-10x / 50 = 40

25x = 40×50

x = 40 × 50 /25

= 80
