Find the median assuming the n is the smallest no. in the group.
median = (15+200)/2
The median cannot be smaller than the above value.
Now find the median assuming n is the largest in the group.
median = (200+250)/2
Here median cannot be larger than the above value.

Now we have got the range of the median.
107.5<=median<=225

Select the values which fall between these nos and you have got your answer.
In this case C.
