{
float percentage;
float total;
float marksObtained;
Scanner sc = new Scanner(System.in);
System.out.println("Please enter marks obtained : ");
marksObtained = sc.nextFloat();
total = sc.nextFloat();
percentage = (float)((marksObtained / total) * 100);
System.out.println("Percentage : " + percentage);
