Question

В первый день овощная палатка продала 1/4 часть всего полученного картофеля, во второй день 360 кг. После этого осталось продать 3/20 всего картофеля. Сколько кг картофеля получила палатка?

Answer 1

Х- весь картофель
х-(1/4х+360)=3/20х
х-1/4х-360=3/20х
х-1/4х-3/20х=360
20/20х-5/20х-3/20х=360
12/20х=360
3/5х=360
х=360: 3/5
х=360*  5/3
х=120* 5/1
х=600кг- получила палатка

Calculation of Potato Sales

To calculate the amount of potatoes the vegetable stand sold, we need to follow the given information step by step.

1. On the first day, the vegetable stand sold 1/4 of the total potatoes. 2. On the second day, the vegetable stand sold 360 kg of potatoes. 3. After these two days, there were still 3/20 of the total potatoes left to sell.

Let's calculate the total amount of potatoes received by the vegetable stand.

Calculation:

1. Let's assume the total amount of potatoes received by the vegetable stand is x kg. 2. On the first day, the vegetable stand sold 1/4 of the total potatoes, which is (1/4)x kg. 3. On the second day, the vegetable stand sold 360 kg of potatoes. 4. After these two days, there were still 3/20 of the total potatoes left to sell, which is (3/20)x kg.

To find the total amount of potatoes received by the vegetable stand, we can set up the following equation:

(1/4)x + 360 + (3/20)x = x

Now, let's solve the equation to find the value of x.

(1/4)x + (3/20)x = x - 360

To simplify the equation, let's find a common denominator for the fractions:

(5/20)x + (3/20)x = x - 360

Combining like terms:

(8/20)x = x - 360

Multiplying both sides of the equation by 20 to eliminate the denominator:

8x = 20x - 7200

Subtracting 20x from both sides:

-12x = -7200

Dividing both sides by -12:

x = 600

Therefore, the vegetable stand received a total of 600 kg of potatoes.

Answer:

The vegetable stand received a total of 600 kg of potatoes.
