A herd of cows is lined up in a row. The first cow is in front of two cows, the last cow is behind two cows, and the cow in the middle is between the other two. How many cows are in the herd?
Answer: There are 3 cows in the herd.
Instructions to Solve:
Visualize the Arrangement: Imagine lining up the cows in a row and apply the conditions given.
Identify the Positions:
The first cow is in front of two cows. This means there must be at least two cows behind it.
The last cow is behind two cows. This means there must be at least two cows in front of it.
The middle cow is between the other two cows, meaning there must be exactly one cow in front of it and one cow behind it.
Determine the Number of Cows:
Place the cows based on these conditions:
With one cow in front of two cows and one cow behind two cows, you need a total of three cows to satisfy these conditions. The middle cow will be the one between the other two.
Count the Cows:
Verify the arrangement:
Cow 1: In front of two cows.
Cow 2: In the middle, between Cow 1 and Cow 3.
Cow 3: Behind two cows.
This arrangement fits all the conditions described.
