Question

Find the arithmetic mean of the sales per day in a fair price shop in a week
$Rs.10000,Rs.10250,Rs.10790,Rs.9865,Rs.15350,Rs.10110$.

Answer 1

Given:

The sales of pair shop in a week are,

$Rs.10000,Rs.10250,Rs.10790,Rs.9865,Rs.15350,Rs.10110$

Number of days $=6$

We know that,

Arithmetic mean $=\frac{\text{sum of all the observations}}{\text{Number of observations}}$

$\Rightarrow$ Arithmetic mean $=\frac{Rs.10000,+Rs.10250+Rs.10790+Rs.9865+Rs.15350+Rs.10110}{6}$

$=\frac{Rs.66365}{6}$

$=Rs.11060.83$ (Approximately)

Therefore, the arithmetic mean of the sales per day in a fair price shop in a week is $Rs.11060.83$ (Approximately)
