public class Exr1 {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the number of Bengali");
        int a = sc.nextInt();
        System.out.println("Enter the number of English");
        int b = sc.nextInt();
        System.out.println("Enter the number of Mathematics");
        int c = sc.nextInt();
        System.out.println("Enter the number of Physics");
        int d = sc.nextInt();
        System.out.println("Enter the number of Chemistry");
        int e = sc.nextInt();
        System.out.println("Total");
        float sum = a+b+c+d+e;
        System.out.println(sum);
        System.out.println("Percentage");
        float percentage = (sum/500) * 100;
        System.out.println(percentage);
    }
