Answer 1

Answer:

public class Q1

{

public static void main(String args[])throws IOException

{

InputStreamReader read =new InputStreamReader(System.in);

BufferedReader in =new BufferedReader(read);

int p; double SI1,SI2,SI3,A3;

System.out.println(“Enter the principal”);

p=Integer.parseInt(in.readLine());

SI1=(p*5.0*1)/100.0;

System.out.println(“Interest for the first year =”+SI1);

SI2=((p+SI1)*5.0*1)/100.0;

System.out.println(“Interest for the second year =”+SI2);

SI3=((SI1+SI2+p)*5.0*1)/100;

A3=SI1+SI2+SI3+p;

System.out.println(“Amount after three years =”+A3);

}

}

Sample Input: 10000

Sample Output: Interest for the first year =500.0

Interest for the second year =525.0

Amount after three years =11576.25
