Solution

The correct option is A 40-50
From above cumulative frequency distribution, we can see that the total number of observations n = 51.
$\frac{n}{2} = 25.5$
The cumulative frequency closest to and above $\frac{n}{2}$ is 33. The class corresponding to this frequency is 40-50.
Thus the median class is 40-50.
