Пошаговое объяснение:

Первого и второго вида купили всего 16 кг

Первого и третьего вида купили всего 15 кг, значит второго вида купили на 1 кг больше чем третьего

Второго и третьего купили всего 21 кг, значит второго вида купили (21 + 1)/2 = 11 кг

Третьего вида купили: 21 - 11 = 10 кг

Первого вида купили: 16 - 11 = 5 кг
