Answer 2

Given,

The numbers that are divisible by 5, between 9 and 32.

To find,

Average of all such numbers.

Solution,

Here, it is required to find the average of all the numbers between 9 and 32 which are divisible by five.

So there are 5 numbers that lie between 9 and 32 and are divisible by 5. These numbers are,

10, 15, 20, 25, 30.

Sum of these numbers will be,

= 10 + 15 + 20 + 25 + 30

= 100.

Now, the average can be determined using the formula,

$average=\frac{sum}{number \hspace{3} of \hspace{3} terms}$

⇒ $average=\frac{100}{5}=20$

⇒ average = 20.

Therefore, the average of all the numbers between 9 and 32 which are divisible by 5 is 20.
