Question

The numbers of apples sold on different days of the week are given as $12,14,17,19,20,21,23$. Find the average of number of apples sold on that particular week.

• A. $19$
• B. $24$
• C. $18$
• D. $14$

Answer 1

The correct option is C $18$

The mean or average of the given data set is calculated as,

$\begin{array}{cc}\text{Mean}& =\frac{\text{Sum of all data points}}{\text{Total number of data points}}\end{array}$

Divide the total number of apples sold in a week by the number of days in a week to obtain the average number of apples sold in a week.

$\begin{array}{cc}\text{Average number of apples}& =\frac{12+14+17+19+20+21+23}{7}\\ & =\frac{126}{7}\\ & =18\end{array}$
