Question

How many numbers between 1 and 100 inclusive are divided by 4 or 9

Answer 1

First, we find how many numbers are divided by 4:

`(100)/(4)=25`

Now, we find how many numbers are divided by 9:

`(99)/(9)=11`

Adding these two results:

`25+11=36`

Finally, we find how many numbers are divided by both 4 and 9:

`36\text{ and }72`

That is, there are two numbers. We subtract 2 from 36 and we obtain 34 numbers.

Answer: 34 numbers
