Correct Answer: 18


Solution : As per the given graph,
The number of students who obtained marks in the interval 0-10 = 2
The number of students who obtained marks in the interval 10-20 = 6
The number of students who obtained marks in the interval 20-30 = 10
The total number of failures = 2 + 6 + 10 = 18
Hence, the correct answer is 18.
