Для начала посчитаем, сколько процентов картофеля было продано за третий день.

1) 100 - (20 + 40) = 40 (процентов) - картофеля продано за третий день.

Далее считаем, сколько килограмм картофеля приходится на один процент.

2) 144 : 40 = 2,85 (килограмм) - картофеля приходится на один процент.

Теперь считаем, сколько килограмм картофеля продали за первый день.

3) 40* 2,85 = 114(килограмм) - всего продали в первый день.

Сейчас находим килограммы картофеля, которые продали во второй день.

4) 20 * 2,85= 57(килограмм) - продали во второй день.

Осталось только найти общее количество кг картофеля, которое привези в магазин.

5) 144 + 57 + 114 = 315 (килограмм) - всего привезли.

ответ: всего в магазин привезли 315 килограмм картофеля.ответ:
