The histogram shows the marks scored by 40 students in a test with maximum 30 marks.
What is the percentage of the students who scored less than 20 marks?
Answer & explanation
Correct answer: option 4
Total number of students = 40
Number of the students who scored less than 20 marks = 2 + 8 + 7 + 8 = 25
Required percentage = \(\frac{25 }{40}\) × 100
= 62.5%
