are there in the pile
​

Answer 1

Answer:

18

Step-by-step explanation:

Let the number of exercise books in the pile be x.

Thickness of each book in the pile                  =  1 / 10 m

Height of the pile                         =  x * 1/10 m  =  9 / 5 m

⇒x / 10 = 9 / 5

⇒5 x = 9 * 10

⇒5x = 90

⇒x = 90 / 5

⇒ x = 18

∴ There are 18 exercise books in the pile.
