A math problem featuring a cow has gone viral, and it’s harder than it looks. The puzzle involves buying and selling a cow in a sequence of transactions, and the challenge is to calculate the final profit correctly.
You buy a cow for $800 and sell it for $1,000, making a $200 profit.
Then you buy it back for $1,100. Since you already made $200, your real cost is $900.
When you sell the cow again for $1,300, your total profit is $400.
Despite its simplicity, many people get confused. But if you followed the numbers closely, you’d see the answer is $400. Did you solve it? If so, you’ve just beaten one of the internet’s trickiest brain teasers!
