Write a program that asks the user to enter an object’s mass, then calls a // function to return the object's weigh in newtown. If the object weighs // more than 500 newtons, the function also displays a message indicating that // it is too heavy. If the object weighs less than 100 newtons, the function // also displays a message indicating that it is too light.

import java.util.Scanner;

public class num8 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter the mass");

       double mass = in.nextDouble();

       double weight = calWeight(mass);

       System.out.println("The weigth is "+weight);

   }

   static double calWeight(double mass){

       double weight = mass*9.80665; // assume a = accelation due to gravity = 9.80665N

       if(weight>500){

           System.out.println("Too Heavy");

       }

       else if(weight<100){

           System.out.println("Too Light");

       }

       return weight;

   }

}

Explanation:

the answer would be 2

since they are only saying that the couple has 20 daughters and so on but they never said that they went to the movies as well therefore the couple was the only people that went to the movies.
