Question

Масса 100 л воды составляет 100 кг, масса 100 л нефти на 10 кг меньше, чем воды, а бензина - на 14 кг меньше, чем нефти. Какая масса 100 л бензина?

Answer 1

1) 100-10 = 90 (кг) - масса 100 л нефти.

2) 90-14 = 76 (кг) - масса 100 л бензина

Ответ: 76 кг

Answer 2

To solve this problem, let's break it down step by step:

1. Given the mass of 100 liters of water is 100 kg.
2. The mass of 100 liters of oil is 10 kg less than that of water.
3. The mass of 100 liters of gasoline is 14 kg less than that of oil.

Let's calculate the mass of 100 liters of oil first:

Mass of 100 liters of oil = Mass of 100 liters of water - 10 kg Mass of 100 liters of oil = 100 kg - 10 kg Mass of 100 liters of oil = 90 kg

Now, let's calculate the mass of 100 liters of gasoline:

Mass of 100 liters of gasoline = Mass of 100 liters of oil - 14 kg Mass of 100 liters of gasoline = 90 kg - 14 kg Mass of 100 liters of gasoline = 76 kg

So, the mass of 100 liters of gasoline is 76 kg.
