=2/5 × 80/80=16/40

Ishan reads3/7 of a book.Now 140 pages left to be read.Find the total no of pages in this book.

Want ans of this question

To find the total number of pages in the book, we can set up an equation. Let's use the variable x to represent the total number of pages in the book.

According to the information given, Sachin has read 3/5 of the book, which means he has read (3/5) * x pages.

We also know that there are 80 pages left to be read. So the remaining number of pages is equal to (x - (3/5) * x) = (2/5) * x.

We can now set up an equation:

(2/5) * x = 80

To solve for x, we can multiply both sides of the equation by (5/2):

x = 80 * (5/2)

x = 200

Therefore, the total number of pages in the book is 200.
