import java.util.*;
public class Q14{
public static void main(String g[]){
int n; // number of years used
double price, drate, dval, amt; // price, depreciationrate, depreciated value
Scanner obj = new Scanner(System.in);
System.out.printIn("Enter the showroom price of the car");
price = obj.nextDouble();
System.out.printIn("Enter the number of years, the car had been used");
n = obj.nextInt();
switch(n)
{ case 0: 
  case 1: drate = 10.0 / 100; break;
  case 2: drate = 20.0 / 100; break;
  case 3: drate = 30.0 / 100; break;
  case 4: drate = 50.0 / 100; break;
default: drate = 60.0 / 100;
}
dval = price * drate;
amt = price − dval; ’
System.out.printIn("\n\nOriginal Price: Rs. " + price);
System.out.printin("Depreciated Value: Rs. " + dval);
System.out.printIn("Amount Paid for the car: Rs. " + amt);
