Question

Piyush reads $\frac{3}{5}$ of a book. He finds that there are still $80$ pages left to be read. Total number of pages in book is ________ .

• A. $100$
• B. $200$
• C. $300$
• D. $400$

Answer 1

Answer: (B)

$200$

We Know,

Piyush has read $\frac{3}{5}$ part of the book.

$\therefore$ Part of book left $=1-\frac{3}{5}=\frac{2}{5}$

Now,

Let Total No. of pages in the book be $x$

$\therefore \frac{2}{5}$ of $x=80$

$⟹x=80\times \frac{5}{2}$

$⟹x=200$

Hence, the book has $200$ pages
