10. Write a program to find the grade of a student when grades are allocated as given in the table below.
Percentage of Marks Grade
Above 90% A
80% to 90% B
70% to 80% C
60% to 70% D
Below 60% E
Percentage of the marks obtained by the student is input to the program.
Ans. percentMarks = float(input('Enter the percentage of the student: '))
if(percentMarks >= 90):
print("Grade A")
elif(percentMarks >= 80):
print("Grade B")
elif(percentMarks >= 70):
print("Grade C")
elif(percentMarks >= 60):
print("Grade D")
else:
print("Grade E")
CASE STUDY-BASED QUESTIONS
Let us add more functionality to our SMIS developed in Chapter 7.
6.1. Write a menu driven program that has options to
• accept the marks of the student in five major subjects in Class X and display the same.
• calculate the sum of the marks of all subjects. Divide the total marks by number of subjects
(i.e. 5), calculate percentage = total marks/5 and display the percentage.
• Find the grade of the student as per the following criteria:
Criteria Grade
percentage > 85% A
percentage < 85 && percentage >= 75 B
percentage < 75 && percentage >= 50 C
percentage < 30 && percentage >= 50 D
percentage < 30 Reappear
Let’s peer review the case studies of others based on the parameters given under “DOCUMENTATION TIPS” at the end of Chapter 7 and
provide a feedback to them.
Ans. def acceptMarks():
marks = []
print("Enter marks for each subject:")
for i in range(5):
subjectMarks = float(input(f"Subject {i+1}: "))
marks.append(subjectMarks)
return marks

def computePercentage(totalMarks):
return totalMarks / 5

def findGrade(percentage):
if percentage > 85:
return 'A'
elif 75 <= percentage < 85:
return 'B'
