Answer 2

The number is 40

Step-by-step explanation:

Let the number be x

One - ninth of number =$\frac{1}{9}x$

One tenth of number = $\frac{1}{10}x$

We are given that one ninth of a certain number exceeds its one tenth by 4

So, $\frac{1}{9}x-\frac{1}{10}x=4\\\\\frac{10x-9x}{10}=4\\\frac{x}{10}=4$

x=40

Hence The number is 40
