First, we prepare the cumulative frequency table for above data

We know that median class of a data is the class-interval corresponding to cumulative frequency just greater than

Where,

As N = 25 therefore

And

Cumulative frequency just greater than 25 is 26 which lies corresponding to class 30-40

Hence, 30-40 is median class.
