Algorithm

·                     Start

·                     Declare sub1, sub2, sub3, marks, avg as float

·                     Write ("marks of first subject")

·                      Read("marks of first subject”)

·                      Write ("marks of second  subject")

·                      Read("marks of second subject”)

·                     Write ("marks of third subject")

·                      Read("marks of third subject”);

·                      marks=sub1+sub2+sub3

·                      avg=marks/3

·                      Read("The average marks”)

·                     stop
