Step-by-Step Calculation
- List of Marks:
The marks obtained by the students are:
59, 46, 31, 23, 27, 40, 52, 35, 29
- Sum of Marks:
Adding these values together:
59 + 46 + 31 + 23 + 27 + 40 + 52 + 35 + 29 = 342
- Total Number of Students:
The total number of students is 9.
- Calculating the Mean:
Mean = Sum of Marks / Total Number of Students
Mean = 342 / 9 = 38
Conclusion
The mean of the marks obtained by the 9 students in Mathematics is 38. Therefore, the correct answer is option 'C'.
