Question

The daily sale of milk (in litres) in a ration shop for eight days is as follows:
$60,40,10,40,4,70,30$ and $10$.

The average daily sale is:

• A. $40$
• B. $33$
• C. $64$
• D. $24$

Answer 1

The correct option is B $33$

We know, Mean is given by,

$\text{Mean}=\frac{\text{Sum of the elements}}{\text{Total number of elements}}$.

Here, number of observations $=8$.

Then, average saily sale
$=\frac{60+40+10+40+4+70+30+10}{8}$
$=\frac{264}{8}=33$ litres.

Hence, option $B$ is correct.
