Фундаменталс решение:

cargo_count = int(input())
total = {'bus': 0, 'truck': 0, 'train': 0}

for i in range(0, cargo_count):
    cargo = float(input())
    total[{cargo >= 12: 'train', cargo < 12: 'truck', cargo < 4: 'bus'}[True]] += cargo

average = (total['bus'] * 200 + total['truck'] * 175 + total['train'] * 120) / sum(total.values())
print(f'{average:.2f}')

for i in ['bus', 'truck', 'train']:
    print(f'{total[i] / sum(total.values()) * 100:.2f}%')
