Здравейте!
Всички проверки минават, но Judge ми дава 50/100.
Задачата е Logistics, от For Loop - More Exercises
Благодаря предварително.

import java.util.Scanner;

public class Logistic {
    public  static void main(String [] args){
        Scanner sc = new Scanner(System.in);

        int numberOfLoads = Integer.parseInt(sc.nextLine());

        int totalTonnage = 0;
        int busTonnage = 0;
        int truckTonnage = 0;
        int trainTonnage = 0;


        for (int i = 0; i < numberOfLoads; i++) {
            int tonnage = Integer.parseInt(sc.nextLine());
            if (tonnage <= 3){
                busTonnage += tonnage;
            }
            if (tonnage >= 4 && tonnage <= 11){
                truckTonnage += tonnage;
            }
            if (tonnage > 12 ){
                trainTonnage += tonnage;
            }
            totalTonnage += tonnage;
        }
        double averagePrice = (busTonnage * 200 + truckTonnage * 175 + trainTonnage * 120 * 1.0) / totalTonnage;
        double busPercent = busTonnage * 1.0 / totalTonnage * 100;
        double truckPercent = truckTonnage * 1.0 / totalTonnage * 100;
        double trainPercent = trainTonnage * 1.0 / totalTonnage * 100;

        System.out.printf("%.2f%n",averagePrice);
        System.out.printf("%.2f%%%n",busPercent );
        System.out.printf("%.2f%%%n",truckPercent);
        System.out.printf("%.2f%%",trainPercent);
    }
