Write a program to input marks in 3 subjects compute average and then calculate grade

Q. Write a program to input marks in 3 subjects; compute average and then calculate grade as per following guidelines:

 
 
 
 
	 
Grade
 
	 
Remarks
 
	 
Marks
 
 
 
	 
A
 
	 
(Level 4, above agency-normalized standards)
 
	 
80% and above
 
 
 
	 
B
 
	 
(Level 3, at agency-normalized standards)
 
	 
70-79%
 
 
 
	 
C
 
	 
(Level 2, below, but approaching agency-normalized standards)
 
	 
60-69%
 
 
 
	 
D
 
	 
(Level 1, well below agency-normalized standards)
 
	 
50-59%
 
 
 
	 
E
 
	 
(Level 1-, too below agency-normalized standards)
 
	 
40-49%
 

 
	 
R
 
	 
(Remedial standards)
 
	 
39% and below
 

 

You can understand by Watching video :-

Answer =

mark1 = int (input ("Enter the mark for subject 1 :- "))
mark2 = int (input ("Enter the mark for subject 2 :- "))
mark3 = int (input ("Enter the mark for subject 3 :- "))
print ("Average marks is :- ", (mark1 + mark2 + mark3) / 3 )
per = ((mark1 + mark2 + mark3) / 300) * 100
print("Percentage :-",per)
if per >= 80 :
    print ("Grade is 'A'")
elif per >= 70 and per <= 79 :
    print ("Grade is 'B'")
elif per >= 60 and per <= 69 :
    print ("Grade is 'C'")
elif per >= 50 and per <= 59 :
    print ("Grade is 'D'")
elif per >= 40 and per <= 49 :
    print ("Grade is 'E'")
elif per <= 39 :
    print ("Grade is 'R'")

Output :-

Enter the mark for subject 1 :- 93
Enter the mark for subject 2 :- 96
Enter the mark for subject 3 :- 85
Average marks is :-  91.33333333333333
Percentage :- 91.33333333333333
Grade is 'A'
