Solution

The correct option is D
24

No. of students in marks interval 40-50 = 7

No. of students in marks interval 50-60 = 8

No. of students in marks interval 60-70 = 9

So, total no. of students having marks above 40 and below 70 = 7+8+9 = 24

The histogram below represents marks of students in a Mathematics exam with passing marks as 30. For finding the number of failed students, what is the class interval that needs to be considered?

A teacher wanted to analyse the performance of two sections of students in a mathematics test of 100 marks. Looking at their performances, she found that a few students got under 20 marks and a few got 70 marks or above. So she decided to group them into intervals of varying sizes as follows: 0 − 20, 20 − 30… 60 − 70, 70 − 100. Then she formed the following table:

Marks

0 − 20

20 − 30

30 − 40

40 − 50

50 − 60
