What is the mean of this data?

• A. $6$
• B. $2$
• C. $3.6$
• D. $3$

Answer 1

The correct option is C $3.6$

Observe the given pictorial representation, the number of pencils sold on different days are given as:


The mean of the given data is calculated as,

$\begin{array}{cc}\text{Mean}& =\frac{\text{Sum of all data points}}{\text{Total number of data points}}\\ & =\frac{3+4+6+3+2}{5}\\ & =\frac{18}{5}\\ & =3.6\end{array}$

Hence, the mean of the given data is $3.6$.
