Answer 1

1) 100- 60=40 (%) - в третий день2) 72т = 40% 72:40х100=180 (т) - во 2 и 3 день вместе3)100-40=60( %) -  во 2 и 3 день вместе180т = 60%  от  всего картофеля180:60х100=300 (т)
Ответ: 300 тонн картофеля

Answer 2

1)100%-40%=60% -после 1 дня осталось всего имевшего картофеля
60%=0,6
2)0,6*0,6=0,36-всего имевшего картофеля было продано во 2 день
3)0.6-0,36  -было продано в третий день всего имевшего картофеля
4)72:0,24=300 - тонн картофеля было на базе

Answer 3

Task Explanation

The task involves calculating the initial amount of potatoes at the vegetable base given the information that 40% of the total amount was released on the first day, 60% of the remaining amount was released on the second day, and the remaining 72 tons were released on the third day.

Calculation

Let's denote the initial amount of potatoes as P.

1. On the first day, 40% of the total amount was released, leaving 60% of the original amount: 0.6P. 2. On the second day, 60% of the remaining amount was released, leaving 40% of the amount from the first day: 0.6P * 0.6 = 0.36P. 3. On the third day, the remaining 72 tons were released, which is 40% of the amount from the second day: 0.36P = 72.

Solution

To find the initial amount of potatoes, we can solve for P using the equation: 0.36P = 72.

Calculation

Let's calculate the initial amount of potatoes: ``` P = 72 / 0.36 P = 200 ```

Answer

The initial amount of potatoes at the vegetable base was 200 tons.
