            m1 = int.Parse(Console.ReadLine());
            m2 = int.Parse(Console.ReadLine());
            m3 = int.Parse(Console.ReadLine());
            total = m1 + m2 + m3;
            avg = total / 3;
            Console.WriteLine("grand total :" + total);
            Console.WriteLine("Average Percentage :" + avg);
            if (avg > 60)

            }
            else
            {
                if (avg > 50 && avg < 60)
                {
                    Console.WriteLine("2nd class");
                }
                if (avg > 40 && avg < 50)
                {
                    Console.WriteLine("3rd class");
