0. If the pass mark is 30, what is the number of failures in both the sections together?
- Option : B
- Explanation : Number of students in Section A obtained
less than 30 marks = 2 + 5 + 10 = 17.
Number of students in Section B obtained less than 30 marks = 4 + 5 + 9 = 18.
Total number of failures in both Sections = 17+ 18 = 35.
