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 secured marks less than 60 is :
-
- 12
- 15
- 33
- 7
Correct Option: C
From the given above histogram , we can see
The number of students who have scored interval 0-20 = 7
The number of students who have scored interval 0-20 = 8
The number of students who have scored interval 0-20 = 18
Students who score less than 60 marks = 7 + 8 + 18 = 33
