Algorithm to calculate total marks of five subject calculate percentage and specify grade
Repeated postings will not get faster or better responses.
To calculate the total marks of five subjects, you need to add the marks obtained in each subject. Once you have the total marks, you can calculate the percentage and specify the grade based on the percentage obtained. Here is an algorithm to accomplish this task:
1. Initialize a variable "totalMarks" to 0.
2. Take input for the marks obtained in each subject (let's call them 'subject1', 'subject2', 'subject3', 'subject4', and 'subject5').
3. Add the marks obtained in each subject to the "totalMarks" variable.
4. Calculate the percentage by dividing the "totalMarks" by the total marks of all subjects (for example, if each subject is out of 100 marks, the total marks would be 500).
- percentage = (totalMarks / (total marks of all subjects)) * 100.
5. Determine the grade based on the percentage obtained:
- If the percentage is greater than or equal to 90, the grade would be 'A+'.
- If the percentage is greater than or equal to 80 and less than 90, the grade would be 'A'.
- If the percentage is greater than or equal to 70 and less than 80, the grade would be 'B'.
- If the percentage is greater than or equal to 60 and less than 70, the grade would be 'C'.
- If the percentage is less than 60, the grade would be 'D'.
6. Output the total marks, percentage, and grade.
Here's a sample implementation in Python:
```python
# Step 1
totalMarks = 0
# Step 2
subject1 = int(input("Enter marks for subject 1: "))
subject2 = int(input("Enter marks for subject 2: "))
subject3 = int(input("Enter marks for subject 3: "))
subject4 = int(input("Enter marks for subject 4: "))
subject5 = int(input("Enter marks for subject 5: "))
# Step 3
totalMarks = subject1 + subject2 + subject3 + subject4 + subject5
# Step 4
totalMarksOfAllSubjects = 500
percentage = (totalMarks / totalMarksOfAllSubjects) * 100
# Step 5
if percentage >= 90:
grade = 'A+'
elif percentage >= 80:
grade = 'A'
elif percentage >= 70:
grade = 'B'
elif percentage >= 60:
grade = 'C'
else:
grade = 'D'
# Step 6
print("Total Marks: ", totalMarks)
print("Percentage: ", percentage)
print("Grade: ", grade)
```
Here is a step-by-step algorithm to calculate the total marks of five subjects, calculate the percentage, and specify the grade:
1. Start the program.
2. Initialize the total_marks variable to 0.
3. Take input for the marks of the first subject.
4. Add the marks to the total_marks variable.
5. Repeat steps 3 and 4 for the remaining four subjects.
6. Calculate the sum by adding all the marks.
7. Calculate the percentage by dividing the total_marks by 500 (assuming each subject has a maximum of 100 marks).
8. Round off the percentage to two decimal places.
9. Create an if-else statement to specify the grade based on the percentage obtained:
- If the percentage is greater than or equal to 90, assign the grade as "A+."
- If the percentage is between 80 and 89.99, assign the grade as "A."
- If the percentage is between 70 and 79.99, assign the grade as "B."
- If the percentage is between 60 and 69.99, assign the grade as "C."
- If the percentage is below 60, assign the grade as "Fail."
10. Display the total marks, percentage, and grade.
11. End the program.
Keep in mind that this is just the algorithm and you will need to implement it into your chosen programming language to get the final desired result.
