Answer 1

Ответ:

Пошаговое объяснение:

100% - 40%= 60 % залишилось

60% * 2/3= 40% продали другого дня

100% - 40% - 40%= 20% продали третього дня і це складає 80 кг

80 кг -  20%

х кг   -  100%

х= 80 * 100% : 20%

х= 400 кг яблук завезли в магазин

Answer 2

To determine how many kilograms of apples were brought to the store, we need to calculate the remaining amount of apples after each day of sales.

Calculation:

- On the first day, 40% of all the apples were sold. - On the second day, 2/3 of the remaining apples were sold. - On the third day, 80 kg of apples were sold.

Let's calculate the remaining amount of apples after each day:

1. First day: - 40% of the apples were sold, which means 60% of the apples remained. - Let's assume the total amount of apples brought to the store is x kg. - Therefore, after the first day, there were 0.6x kg of apples remaining.

2. Second day: - 2/3 of the remaining apples were sold, which means 1/3 of the apples remained. - After the first day, there were 0.6x kg of apples remaining. - Therefore, after the second day, there were (1/3) * 0.6x = 0.2x kg of apples remaining.

3. Third day: - 80 kg of apples were sold. - After the second day, there were 0.2x kg of apples remaining. - Therefore, after the third day, there were 0.2x - 80 kg of apples remaining.

To find the initial amount of apples brought to the store, we need to solve the equation:

0.2x - 80 = 0

Solving for x:

0.2x = 80

x = 80 / 0.2

x = 400

Therefore, 400 kilograms of apples were brought to the store.

Please note that this calculation assumes that no additional apples were brought to the store during the three days mentioned.
