Question

3. Магазин в течение трех дней продал весь завезённый картофель. В первый день продали 32% всего картофеля, во второй – 40%, а в третий – остальные 224 кг. Сколько килограммов картофеля было завезено в магазин?

Answer 1

Примем за 100% весь завезенный картофель.
1) 32+40=72% картофеля продали в первые два дня.
2) 100-72=28% продали в третий день.
3) пропорция:
28% - 224 кг
100% - х
х = 224•100/28 = 8•100 = 800 кг картофеля завезли.
Ответ: 800 кг.

Answer 2

1 - весь картофель, тогда 0.32х продали в первый день, 0.4х - во второй и (1-(0.32+0.4))х - в третий, что по условию равно 224 кг.

(1-(0.32+0.4))х=224
(1-0.72)х=224
0.28х=224
х=800

Ответ: 800 кг картофеля.

Answer 3

Calculation of the Total Amount of Potatoes Sold

To calculate the total amount of potatoes sold, we need to determine the amount sold on each day and then add them together.

According to the information provided, the store sold 32% of the total potatoes on the first day, 40% on the second day, and the remaining 224 kg on the third day.

Let's assume the total amount of potatoes brought to the store is represented by the variable "x."

On the first day, 32% of the total potatoes were sold, which can be calculated as 0.32x.

On the second day, 40% of the total potatoes were sold, which can be calculated as 0.40x.

On the third day, the remaining 224 kg of potatoes were sold.

To find the total amount of potatoes sold, we can add the amounts sold on each day:

0.32x + 0.40x + 224 = x

Simplifying the equation:

0.72x + 224 = x

Subtracting 0.72x from both sides:

224 = 0.28x

Dividing both sides by 0.28:

x = 800 kg

Therefore, the total amount of potatoes brought to the store was 800 kg.
