Answer 2

Let the total pages be x

Number of pages read = 7/9 of x

= 7 / 9 × x

= 7x / 9

According to Question,

Total number of pages = x

7x / 9 + 40 = x

⇒ (7x + 360) / 9 = x

⇒ 7x + 360 = 9x

⇒ 360 = 9x - 7x

⇒ 360 = 2x

⇒ 360 / 2 = x

⇒ 180 = x

As, x is the total number of pages

Hence, 180 is the total number of pages
