Answer 3

Problem Analysis

We are given two banks, and the first bank has twice as much milk as the second bank. If we pour 0.5 liters from the first bank and add it to the second bank, the amount of milk in both banks will be equal. We need to determine how much milk is in each bank.

Solution

Let's assume that the amount of milk in the second bank is x liters. Since the first bank has twice as much milk as the second bank, the amount of milk in the first bank is 2x liters.

When we pour 0.5 liters from the first bank, the amount of milk remaining in the first bank is 2x - 0.5 liters. When we add 0.5 liters to the second bank, the amount of milk in the second bank becomes x + 0.5 liters.

According to the problem statement, after this transfer, the amount of milk in both banks is equal. Therefore, we can set up the following equation:

2x - 0.5 = x + 0.5

Simplifying the equation, we get:

2x - x = 0.5 + 0.5

x = 1

So, the second bank initially had 1 liter of milk, and the first bank had twice as much, which is 2 liters.

Answer

There is 2 liters of milk in the first bank, and 1 liter of milk in the second bank.
