Фундаменталс решение:

mountains = {'musala': 0, 'montBlanc': 0, 'kilimanjaro': 0, 'k2': 0, 'everest': 0}
group_numbers = int(input())

for i in range(group_numbers):
    group_num = int(input())
    destination = {group_num > 0: 'musala',
                   group_num > 5: 'montBlanc',
                   group_num > 12: 'kilimanjaro',
                   group_num > 25: 'k2',
                   group_num > 40: 'everest'}

    mountains[destination[True]] += group_num

for mountain in mountains.values():
    print(f'{mountain / sum(mountains.values()) * 100:.2f}%')
