Answer 2

Given: $10,20,30$

We have to find the mean of the above data.

As we know that the mean of a data set is the sum of the terms divided by the total number of terms.

The formula for mean is:

$\text { Mean }=\frac{\text { Sum of terms }}{\text { Number of terms }}$

We are solving in the following way:

We have,

$10,20,30$

Here,

$\text { Sum of terms }=10+20+30=60\\\text { Number of terms }=3$

Now, the mean of the given data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\text { Mean } &=\frac{60}{3} \\\text { Mean } &=20\end{aligned}$

Hence, we get,

$\begin{aligned}\text { Mean } &=20\end{aligned}$
