The given histogram shows the marks scored by 40 students in a test of maximum 30 marks.
What is the percentage of students who scored less than 50% marks?
Answer & explanation
Correct answer: option 4
Total number of students = 40
Number of students who scored less than 50% marks = 2 + 8 + 7 = 17
Percentage of students who scored less than 50% marks = \(\frac{17 }{40}\) × 100
= \(\frac{17 }{2}\) × 5
= 42.5%
