Question

Reema reads 1/5 th pages of a book. If she reads further 40 pages, she would have read 7/10th page of the book. How many pages are left to be read?

Answer 1

Answer:

2/3 of x + 40 = 7/10 of x

2x/3 + 40 = 7x / 10

7x /10 - 2x/3 = 40

21x 20x / 30 = 40

x / 30 = 40

x = 1200

1200 × 7/10 = 840 pages are read

and 1200 - 840 = 360

So this means there are 360 pages left to be read.

\begin{gathered}answer = > 360pages \\ \end{gathered}

answer=>360pages

Answer 2

actually , 1/5th = 2/10 before

after

7/10 th of total pages in book = 40 + 2/5

so , 360 pages are left
