Question

3) Свежие грибы содержат 90% воды, а сушеные- 12%. Сколько получиться сушеных грибов из 88 кг свежих?

Answer 1

1) 100%-90%=10% - приходится на сухое вещество в свежих грибах

2) 88:10%=8,8 кг - масса сухого вещества в свежих грибах и сушеных грибах

3) 100%-12%=88% - приходится на сухое вещество в сушеных грибах

4) 8,8:88*100 = 10 кг - масса сушеных грибов

Answer 2

Calculating the Weight of Dried Mushrooms from Fresh Mushrooms

To calculate the weight of dried mushrooms from fresh mushrooms, we can use the information that fresh mushrooms contain 90% water, while dried mushrooms contain 12% water.

Step 1: Calculate the Weight of Water in Fresh Mushrooms The weight of water in fresh mushrooms can be calculated using the formula: \[ \text{Weight of water in fresh mushrooms} = \text{Weight of fresh mushrooms} \times \left( \frac{90}{100} \right) \]

\[ \text{Weight of water in fresh mushrooms} = 88 \, \text{kg} \times \left( \frac{90}{100} \right) \]

\[ \text{Weight of water in fresh mushrooms} = 88 \, \text{kg} \times 0.9 = 79.2 \, \text{kg} \]

Step 2: Calculate the Weight of Solids in Fresh Mushrooms The weight of solids in fresh mushrooms can be calculated using the formula: \[ \text{Weight of solids in fresh mushrooms} = \text{Weight of fresh mushrooms} - \text{Weight of water in fresh mushrooms} \]

\[ \text{Weight of solids in fresh mushrooms} = 88 \, \text{kg} - 79.2 \, \text{kg} = 8.8 \, \text{kg} \]

Step 3: Calculate the Weight of Dried Mushrooms The weight of dried mushrooms can be calculated using the formula: \[ \text{Weight of dried mushrooms} = \text{Weight of solids in fresh mushrooms} \times \left( \frac{100}{88} \right) \]

\[ \text{Weight of dried mushrooms} = 8.8 \, \text{kg} \times \left( \frac{100}{88} \right) \]

\[ \text{Weight of dried mushrooms} = 8.8 \, \text{kg} \times 1.1364 = 9.972 \, \text{kg} \]

Answer: The weight of dried mushrooms from 88 kg of fresh mushrooms would be approximately 9.972 kg.
