We can find the class marks of the given class intervals by using the following formula. 

Class mark = upper class limit + lower class limit / 2 

Taking class marks on x-axis and frequency on y-axis and choosing an appropriate scale (1 unit = 3 for y-axis), the frequency polygon can be drawn as follows. 

It can be observed that the performance of students of section ‘A’ is better than the students of section ‘B’ in terms of good marks.
