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?

42.5

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%
