Find the range of marks of students in a class given as 60, 96, 28, 35, 10, 40, 9, 85 and 25.

Correct option is B

1. Given:

- Marks of students: 60, 96, 28, 35, 10, 40, 9, 85, 25
- We need to find the range of marks.

2. Concept/Formula Used:

- The range of a dataset is the difference between the highest value and the lowest value:
Range = Maximum value - Minimum value

3. Solution:

- Identify the maximum and minimum values:
- Maximum value = 96
- Minimum value = 9
- Calculate the range:
Range = 96 - 9 = 87

4. Answer:

Option B: 87
