1.  Write a Python program to input marks of five subjects Physics, Chemistry, Biology, Mathematics and Computer. Calculate percentage and grade according to following:
Percentage >= 90% : Grade A
Percentage >= 80% : Grade B
Percentage >= 70% : Grade C
Percentage >= 60% : Grade D
Percentage >= 40% : Grade E
Percentage < 40% : Grade F

Solution:-

rno = 5
name = “abc”
physics = 95
chemistry = 93
biology = 96
mathematics= 89
computer = 89
tot = physics + chemistry + biology + mathematics + computer
perc = tot//5
print(“Your roll no is :- “,rno)
print(“Your name is :-“,name)
print(“The total marks you gained :- “,tot)
print(“Your Grade is :- “,perc)
if perc >=90:
print(“Grade A”)
elif perc >=80:
print(“Grade B”)
elif perc>=70:
print(“Grade C”)
elif perc>=60:
prit(“Grade D”)
elif perc>=40:
print(“Grade E”)
else:
print(“Grade F”)

 

Output :-

Solution :- 

Dynamic

rno = int(input(“Enter the roll no :-“))

name = input(“Enter your name :-“)

physics = int(input(“Enter the marks of physics :-“))

chemistry = int(input(“Enter the marks of Chemistry :-“))

biology = int(input(“Enter the marks of Biology :-“))

mathematics= int(input(“Enter the marks of Maths :-“))

computer = int(input(“Enter the marks of Computer :-“))

tot = physics + chemistry + biology + mathematics + computer

perc = tot//5

print(“Your roll no is :- “,rno)

print(“Your name is :-“,name)

print(“The total marks you gained :- “,tot)

print(“Your Grade is :- “,perc)

if perc >=90:

    print(“Grade A”)

elif  perc >=80:

    print(“Grade B”)

elif perc>=70:

    print(“Grade C”)

elif perc>=60:

    prit(“Grade D”)

elif perc>=40:

    print(“Grade E”)

else:

    print(“Grade F”)

 
Output :-
