Problem Analysis

The problem states that a farmer had 27 chickens. Every 3 chickens were exchanged for 2 ducks, and then every 3 ducks were exchanged for 2 geese. We need to determine how many geese the farmer ended up with.

Solution

To solve this problem, we can break it down into steps:

1. Start with 27 chickens. 2. Exchange every 3 chickens for 2 ducks. 3. Exchange every 3 ducks for 2 geese.

Let's calculate the number of geese step by step.

Step 1: Chickens

The farmer starts with 27 chickens.

Step 2: Ducks

Every 3 chickens are exchanged for 2 ducks. To calculate the number of ducks, we divide the number of chickens by 3 and multiply by 2.

Number of ducks = (Number of chickens / 3) * 2

Number of ducks = (27 / 3) * 2 = 9 * 2 = 18 ducks

Step 3: Geese

Every 3 ducks are exchanged for 2 geese. To calculate the number of geese, we divide the number of ducks by 3 and multiply by 2.

Number of geese = (Number of ducks / 3) * 2

Number of geese = (18 / 3) * 2 = 6 * 2 = 12 geese

Therefore, the farmer ended up with 12 geese.

Answer

The correct answer is Г) 12.
