Question

19. The Simple Interest (SI) and Compound Interest (CI) of a sum (P) for a given
time (T) and rate (R) can be calculated as:
(1) CI ={[1+r/100]t-1}
(a) SI = p*r*t\100

Write a program to input sum, rate, time and type of Interest ('S' for Simple
Interest and 'C' for Compound Interest). Calculate and display the sum and the interest earned​

Answer 1

Answer:

SI AND CI ARE FOLLOWS

Explanation:

IN PYTHON....

print(" 'S' for simple interest ")

print(" 'C' for compound interest")

a=input("ENTER THE INTEREST TYPE ")

if a=='S':

      p=int(input("enter principal amount "))

      r=int(input("enter rate of interest "))

      t=int(input(" enter time "))

      s=p*r*t/100

      print("simple interest of your given values = ",s)

SAME FOR CI ALSO.....

Answer 2

Answer:

import java.util.Scanner;

public class Interest

{

  public static void main(String args[])  

  {

       Scanner in = new Scanner(System.in);

       System.out.println("Program to find the Simple Interest (SI) and Compound Interest (CI)");

       System.out.print("Enter the sum:");

       double p = in.nextDouble();

       System.out.print("Enter the rate of interest:");

       double r = in.nextDouble();

       System.out.print("Enter the time in years:");

       int t = in.nextInt();

       System.out.println("Enter type of Interest");

       System.out.print("'S'- Simple Interest 'C'- Compound Interest: ");

       char type = in.next().charAt(0);  

       double SI,CI,amt;

       switch(type)

       {

           case 'S': SI= p*r*t/100;

                     amt = p + SI;

                     System.out.println("Sum = " + p);

                     System.out.println("Interest = " + SI);

                     System.out.println("Sum + Interest = " + amt);

                     break;

           case 'C': CI= p*(Math.pow((1+(r/100)),t)-1);

                     amt = p + CI;

                     System.out.println("Sum = " + p);

                     System.out.println("Interest = " + CI);

                     System.out.println("Sum + Interest = " + amt);

                     break;

           default:System.out.println("Wrong Coice");

       }            

  }

}
