Question

При сушке малина теряет 75% своей массы. Сколько нужно взять малины, чтобы получить 15 кг. сушеных ягод? Сколько сушеной малины получится из 40 кг. свежей?Задачу саму решил, но не знаю как записать условие.

Answer 1

1) 100% - 75% = 25% составляют сушенные ягоды
2) 15 : 25% = 15 : 25/100 = 60 кг надо взять ягод
3) 40 * 25% = 10 кг получится сушенных ягод из 40 кг

Answer 2

Problem Statement

You want to know how much fresh raspberries you need to obtain 15 kg of dried berries, as well as how much dried raspberry you will get from 40 kg of fresh berries.

Solution

To solve this problem, we need to consider the fact that raspberries lose 75% of their mass during the drying process. Let's calculate the required amount of fresh raspberries to obtain 15 kg of dried berries.

Let's assume that the initial mass of fresh raspberries is x kg. After drying, the mass of the raspberries will be reduced by 75%, which means the mass of dried raspberries will be 25% of the initial mass.

We can set up the following equation to solve for x:

0.25x = 15

To find the value of x, we can divide both sides of the equation by 0.25:

x = 15 / 0.25

Now, let's calculate the value of x:

x = 60

Therefore, you would need 60 kg of fresh raspberries to obtain 15 kg of dried berries.

Now, let's calculate how much dried raspberry you will get from 40 kg of fresh berries.

Since the raspberries lose 75% of their mass during drying, the mass of dried raspberries will be 25% of the mass of fresh raspberries.

We can set up the following equation to solve for the mass of dried raspberries:

0.25 * 40 = y

To find the value of y, we can calculate:

y = 0.25 * 40

Now, let's calculate the value of y:

y = 10

Therefore, you will get 10 kg of dried raspberries from 40 kg of fresh berries.

In summary: - To obtain 15 kg of dried berries, you would need 60 kg of fresh raspberries. - From 40 kg of fresh raspberries, you will get 10 kg of dried raspberries.
