The Correct Option is C
Solution and Explanation
- The total number of students is 20, and the average score is 15.
Step 1: Calculate Total Marks
The total marks scored by all students is calculated as follows:
Total marks = 20 × 15 = 300
Step 2: Marks Scored by 5 Students
- Out of these 20 students, 5 students scored 0 marks. The total marks scored by these 5 students is:
0 × 5 = 0
Step 3: Marks Scored by the Remaining 15 Students
- The total marks scored by the remaining 15 students is:
300 - 0 = 300
Step 4: Calculate the Average Marks of the Remaining 15 Students
The average marks of the remaining students is calculated as follows:
Average = 300 ÷ 15 = 20
Conclusion: The average marks of the remaining students is 20.
