Solution

The correct option is D $7.5$
$\Rightarrow$ Factors of $24$ are $1, 2, 3, 4, 6, 8, 12, 24$
So, the observations are $1, 2, 3, 4, 6, 8, 12, 24$
$∴$ Number of observations $= 8$
Arithmetic mean $= \frac{Sum of observations}{Number of observations}$

$∴$ Arithmetic mean $= \frac{1 + 2 + 3 + 4 + 6 + 8 + 12 + 24}{8}$

$∴$ Arithmetic mean $= \frac{60}{8}$

$∴$ Arithmetic mean $= 7.5$
