Yes, I’ve seen that math puzzle with the cow making the rounds on Twitter! It’s sparked a lot of debate, but here’s the correct solution:
Buy the cow for $800.
Sell it for $1000, earning a $200 profit.
Re-purchase it for $1100, but with the $200 profit, your effective cost is $900.
Sell it again for $1300, earning a $400 profit ($1300 – $900).
So, the total profit is $400.
