To find the total number of students, we need to sum the number of students in each marks range. Let's start adding the numbers step-by-step based on the given data:
1. Marks range 0-5: 6 students
2. Marks range 5-10: 18 students
3. Marks range 10-15: 20 students
4. Marks range 15-20: 15 students
5. Marks range 20-25: 2 students
6. Marks range 25-30: 4 students
7. Marks range 35-40: 1 student
8. Marks range 40-45: 20 students
9. Marks range 45-50: 10 students
Now, let's add these quantities together:
6 (students in 0-5)
+ 18 (students in 5-10)
+ 20 (students in 10-15)
+ 15 (students in 15-20)
+ 2 (students in 20-25)
+ 4 (students in 25-30)
+ 1 (student in 35-40)
+ 20 (students in 40-45)
+ 10 (students in 45-50)
When we sum these values, we get the total number of students:
6 + 18 + 20 + 15 + 2 + 4 + 1 + 20 + 10 = 96
Therefore, the total number of students is 96.
