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

The given problem is solved using language - Java.

import java.util.*;

public class Brainly{

   public static void main(String s[]){

       double principal,rate,time,si=0,amount;

       Scanner sc=new Scanner(System.in);

       System.out.print("Enter principal amount: ");

       principal=sc.nextDouble();

       System.out.print("Enter time period in months: ");

       time=sc.nextDouble();

       sc.close();

       if(time<=0)

           System.out.println("Invalid Choice. Program terminated.");

       else{

           if(time<=6){

               si=principal*5.0*time/100;

           }

           else if(time<=12){

               si=(principal*5*6/100)+(principal*5.5*(time-6)/100);

           }

           else if(time<=24){

               si=((principal*5*6)+(principal*5.5*6)+(principal*6.0*(time-12)))/100;

           }

           else if(time<=36){

               si=((principal*5*6)+(principal*5.5*6)+(principal*6.0*12)+(principal*6.5*(time-24)))/100;

           }

           else{

               si=((principal*5*6)+(principal*5.5*6)+(principal*6*12)+(principal*6.5*12)+(principal*7*(time-36)))/100;

           }

           amount=principal+si;

           System.out.println("Amount: "+amount);

       }

   }

}

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

1. Accept the principal and time from the user.
2. Check if the entered data is valid or not.
3. If valid, calculate the rate of interest as per the conditions given.
4. Using formula SI = PTR/100, calculate the simple interest.
5. Calculate Amount using formula A = P + SI.
6. Display the amount.
