#5. Read marks of Physics, Chemistry and Mathematics from the user and calculate average and Grade. Write a  Python Program to print the Grade according to the following Table:
#       Average         Grade
#       >=90            O
#    80<= and >90       A
#    70<= and >80       B
#    60<= and >70       C
#    50<= and >60       D
#       <50            Fail
