$\texttt{\textsf{\large{\underline{Solution}:}}}$

The given problem is solved using language - Java.

import java.util.*;

public class Brainly{

   public static void main(String s[]){

       double BS,DA,SA,GS;

       Scanner sc=new Scanner(System.in);

       System.out.print("Enter basic salary: ");

       BS=sc.nextDouble();

       if(BS<0){

           System.out.println("Invalid Input.");

       }

       else{

           if(BS<=10000){

               DA=15.0/100.0*BS;

               SA=5.0/100.0*BS;

           }

           else if(BS<=20000){

               DA=20.0/100.0*BS;

               SA=8.0/100.0*BS;

           }

           else if(BS<=30000){

               DA=25.0/100.0*BS;

               SA=10.0/100.0*BS;

           }

           else{

               DA=30.0/100.0*BS;

               SA=12.0/100.0*BS;

           }

           GS=BS+DA+SA;

           System.out.println("Basic\tDA\tSpl. Allowance\tGross Salary");

           System.out.println(BS+"\t"+DA+"\t"+SA+"\t\t"+GS);

           sc.close();

       }

   }

}

$\texttt{\textsf{\large{\underline{Logic}:}}}$

• Accept the basic salary as input.
• Check if the basic salary is valid or not.
• If valid, calculate DA and SA as per the conditions given.
• Add basic, DA and SA and store them in variable GS.
• Display the result in tabular form.

See attachment for output.

Answer 2

Answer:

Program:-

import java.util.*;

public class Main

{

public static void main(String args[])

{

Scanner in=new Scanner(System.in);

int bp;

double da=0,sa=0,gs=0;

System.out.println("Enter the basic pay of the employee:");

bp=in.nextInt();

if(bp<=10000)

{

da=15.0/100.0*bp;

sa=5.0/100.0*bp;

gs=bp+da+sa;

}

else if(bp>10000&&bp<=20000)

{

da=20.0/100.0*bp;

sa=8.0/100.0*bp;

gs=bp+da+sa;

}

else if(bp>20000&&bp<=30000)

{

da=25.0/100.0*bp;

sa=10.0/100.0*bp;

gs=bp+da+sa;

}

else if(bp>30000)//The statements after else are optional even you don't place any condition the compiler will treat it as it is.

{

da=30.0/100.0*bp;

sa=12.0/100.0*bp;

gs=bp+da+sa;

}

System.out.println("Basic\t\t"+"DA\t\t\t"+"Spl. Allowance\t"+"Gross Salary"); System.out.println(bp+"\t"+da+"\t\t\t"+sa+"\t\t\t\t\t\t\t"+gs);

in.close();

}

}

Output is attached.

Logic:-

• Declare basic pay and declare and initialize variables da,sa and gs.
• See the conditions and use nested if else statement
• Finally print and display the output as per the given format given in the question.
• For formatting use escape sequence "\t" which must be enclosed within double quotes.
