The Cow Math Puzzle: A Brain Teaser for the Curious Mind
- You buy a cow for $800.
- You sell the cow for $1000, making a profit of $200.
- You buy the cow again for $1100, but since you already made a profit of $200 from the first transaction, your effective cost for the second purchase is reduced to $900.
- Finally, you sell the cow again for $1300, making a profit of $400 ($1300 – $900).
