10. Write a Java program to input marks of five subjects Physics, Chemistry, Biology, Mathematics and Computer. Calculate percentage and grade according to following:

Percentage >= 90% : Grade A

Percentage >= 80% : Grade B

Percentage >= 70% : Grade C

Percentage >= 60% : Grade D

Percentage >= 40% : Grade E

Percentage < 40% : Grade F

Static

Solution :-

class result
{
   public static void main(String args[])
   {
   int che = 55,phy=70,bio=65,maths=85,comp=80,tot,perc;
   tot = che+phy+bio+maths+comp;
   perc =tot/5;
   System.out.println("The total marks your score is :-"+tot);
   System.out.println("The percentage you scored is :- "+perc);
   if (perc>=90)
   {
        System.out.println("Your grade is A :- "+perc);
   }
   else if (perc>=80)
   {
        System.out.println("Your grade is B :- "+perc);
   }
   else if (perc>=70)
   {
        System.out.println("Your grade is C :- "+perc);
   }
   else if (perc>=60)
   {
        System.out.println("Your grade is D :- "+perc);
   }
   else if (perc>=40)
   {
        System.out.println("Your grade is A :- "+perc);
   }
   else if (perc<40)
   {
        System.out.println("Your grade is A :- "+perc);
   }
   else
   {
        System.out.println("Fail");
   }
      }
}

Output :-

Dynamic

Solution :-

import java.util.*;
class result
{
   public static void main(String args[])
   {


   int che,phy,bio,maths,comp,tot,perc;
   Scanner in = new Scanner(System.in);

   che =in.nextInt();
   System.out.println("Enter the marks of Biology :- ");
   bio =in.nextInt();
   System.out.println("Enter the marks of Mathematics :- ");
   maths =in.nextInt();
   System.out.println("Enter the marks of Computer :- ");
   comp =in.nextInt();
   tot = che+phy+bio+maths+comp;
   perc =tot/5;
   System.out.println("The total marks your score is :-"+tot);
   System.out.println("The percentage you scored is :- "+perc);
   if (perc>=90)
   {
        System.out.println("Your grade is A :- "+perc);
   }
   else if (perc>=80)
   {
        System.out.println("Your grade is B :- "+perc);
   }
   else if (perc>=70)
   {
        System.out.println("Your grade is C :- "+perc);
   }
   else if (perc>=60)
   {
        System.out.println("Your grade is D :- "+perc);
   }
   else if (perc>=40)
   {
        System.out.println("Your grade is A :- "+perc);
   }
   else if (perc<40)
   {
        System.out.println("Your grade is A :- "+perc);
   }
   else
   {
        System.out.println("Fail");
   }

}
}

Class 10th Chapter 7 Functions in Calc

Functions in Calc Calc provide built-in standard functions for mathematical, logical, statistical, date and time, financial and other calculations on numbers and text. The process of inserting a function is similar for all functions.That is, to use a function we need to enter a correct spelling of the function along with necessary arguments. This is known as syntax of the functions. t is possible to loose the grip on it and easy to introduce errors. To avoid this, you may take help of function wizard. The Calc support some more functions that support logical decision making. These functions are AND, OR, and NOT. (1) In which of the following ways we can enter a function in Calc ? (a) Directly typing function name in a cell nan (b) Function wizard or selecting from tool bar (c) A and B both (d) Depends on functions (2) A function can start with which of the following options ? (a) '='sign (b) Alphabets (c) Numbers (d) Any of these (3) Which of the following is not a logical...

11. Write a Java program to input basic salary of an employee and calculate its Gross salary according to following: Basic Salary <= 10000 : HRA = 20%, DA = 80% Basic Salary <= 20000 : HRA = 25%, DA = 90% Basic Salary > 20000 : HRA = 30%, DA = 95% Static Solution :- class salary { public static void main(String args[]) { double basic=20000.50,gross,da,hra; if(basic <=10000) { da = basic * 0.8; hra = basic *0.2; } else if(basic <=20000) { da = basic * 0.9; hra = basic *0.25; } else { da = basic * 0.95; ...
