This one is easy..
Here's Approach
There are a total of 300 students and we are required to find the Median height....Since the median height of students will equal to the height of the students in median range so the is.....
Median of 300 is 150 and 151th student ..
Staring in ascending order. These students will lie in range of 4.5H<5 since
25 +60 + 80=165...
Hence the median is in range of 4.5H<5
B correct
