In recent weeks, a simple yet tricky math puzzle involving a cow has been circulating widely across social media platforms. Many users have described it as surprisingly confusing at first glance, even though the solution relies on basic arithmetic and careful tracking of transactions. The puzzle is often presented in a storytelling format, which makes it feel more complex than it actually is. Because of this, it has sparked discussion, debate, and curiosity among people trying to verify their answers.
At the center of the puzzle is a sequence of buying and selling actions involving a cow and a series of prices. While the numbers themselves are not difficult to understand, the challenge lies in keeping track of profit across multiple transactions. Many people make mistakes by double-counting profit or misunderstanding how net gain works over repeated purchases and sales. This is what makes the puzzle both engaging and slightly misleading at first reading.

Step 1: First Purchase and Sale
The scenario begins with a simple transaction. A cow is purchased for $800. Later, it is sold for $1,000. At this stage, the calculation is straightforward: the difference between the selling price and the purchase price results in a profit of $200. This part is easy to understand and serves as the foundation for the rest of the puzzle.
However, this initial profit is often where confusion begins. Some people assume that this $200 must be added repeatedly later, but in reality, each transaction must be tracked separately. The key is to treat each buy-and-sell cycle independently before combining results at the end. This ensures accuracy when calculating total profit.
