30 баллов!!!

7 ребят сидят на чаепитии. У каждого есть чашка с чаем, но не обязательно у всех чая поровну. Они играют в увлекательную игру: каждый по очереди разливает весь свой чай поровну в чашки всем остальным. Когда последний разлил свой чай, у всех ребят осталось столько же чая, сколько было в начале. Сколько чая в каждой чашке, если известно что чая заварили всего 3 литра?

Последний разлил свой чай значит чая у него нет
Получается 3/6=0.5л это по 500 мл чая
alex161shalygin: Во-первых по 500, а во-вторых нужно разъяснение. Всё равно спасибо.
alex161shalygin: По 500 мл - неправильный ответ. Я разрисовал такой вариант - в конце после 7 разливаний поровну у всех ребят кроме последнего (у последнего 0) остаётся разное количество чая в чашках (от первого к шестому идёт на уменьшение) Так что изначально должно быть у всех разное количество чая - это точно.
