Question

The mean of the first five whole numbers is-

• A. $2$
• B. $3$
• C. $3\frac{1}{3}$
• D. none of these

Answer 1

The correct option is A

$2$

The first five whole numbers are $0,1,2,3,4$

Sum of numbers$=0+1+2+3+4$

$=10$

Total numbers$=5$

Therefore,

Mean $=\frac{\mathbf{S}\mathbf{u}\mathbf{m}\mathbf{}\mathbf{o}\mathbf{f}\mathbf{}\mathbf{n}\mathbf{u}\mathbf{m}\mathbf{b}\mathbf{e}\mathbf{r}\mathbf{s}}{\mathbf{T}\mathbf{o}\mathbf{t}\mathbf{a}\mathbf{l}\mathbf{}\mathbf{n}\mathbf{u}\mathbf{m}\mathbf{b}\mathbf{e}\mathbf{r}\mathbf{s}}$

$$\begin{gathered} =\frac{10}{5} \\ =2 \end{gathered}$$

so, the mean of the first five whole numbers is $2$

Hence, option A is correct
