Let’s dissect the transactions: Initially, you spent $800 and then sold the cow for $1,000. This transaction alone netted you a profit of $200.
However, the puzzle doesn’t end there. You then reinvest $1,100 into purchasing the cow again. When you sell it for $1,300, you gain another $200.
Adding these together, your total profit from both transactions is $400.
Sometimes, the simplest arithmetic problems can be the most satisfying to solve, especially when they catch you off guard with their sneaky twists.
