Direction: Study the histogram of marks (in Mathematics) distribution of 50 students of class IX and answer the following questions.
-
The number of students who have scored between 39 and 80 is :
-
- 22
- 18
- 37
- 15
Correct Option: A
From the given above histogram , we can see
The number of students who have scored interval 40-60 = 18
The number of students who have scored interval 60-80 = 4
Required answer = The number of students who have scored interval 40-60 + The number of students who have scored interval 60-80
∴ Required answer = 18 + 4 = 22
