Grade System

• Problem Description

  
  Write a python function to calculate the GRADE systems of marks
  
  Refer sample input and output for formatting specification.
  
  All float values are displayed correct to 2 decimal places.
  
  All text in bold corresponds to input and the rest corresponds to output
  
  Input :
  Input 5 numbers
  
  Output:
  
  1. If the average is above 90 then print Grade as "A" (Hint : 90 and above)
  2. If the average is above 70 and less than 90 then print Grade as "B" (Hint: 71-89)
  3. If the average is above 50 and less than 70 then print Grade as "C"(Hint: 51-70)
  4. If the average is 50 or less then then print as "D"
  

• CODING ARENA

• a=int(input())

  b=int(input())

  c=int(input())

  d=int(input())

  e=int(input())

  n=(a+b+c+d+e)/5

  
  

  if(n>=90):

      print("Grade:A")

  elif(n>=71 and n<90):

      print("Grade:B")

  elif(n>=51 and n<71):

      print("Grade:C")

  else:

      print("Grade:D")
