       Scanner sc = new Scanner(System.in);
       int age = sc.nextInt();
       double mercuryAge = age*365.0/88;
       double VenusAge = age*365.0/225;
       double JupiterAge = age*365.0/4380;
       double SaturnAge = age*365.0/10767;

       System.out.println("Age on Venus "+VenusAge);
       System.out.println("Age on Jupiter "+JupiterAge);
       System.out.println("Age on Saturn "+SaturnAge);
