Solution

The correct option is C $30$
Arranging the data in ascending order:
$24, 25, 26, 28, 30, 30, 32, 33, 34, 35$
Mean $= \frac{sum of all numbers}{count of all numbers} = \frac{24 + 25 + 26 + 28 + 30 + 30 + 32 + 33 + 34 + 35}{10} = \frac{297}{10} = 29.7$
Median of even number of data is the average of the middle two terms that is here the average of $5^{t h}$ and $6^{t h}$ terms.
Median $= \frac{30 + 30}{2} = 30$
