Puzzles like this one often spark debate and confusion. If you’re reading this, you probably enjoy unraveling tricky situations or perhaps stumbled upon this puzzle and want to test your problem-solving skills. So here’s the challenge: Anna buys a cow, sells it, buys it back, and sells it again. But did she end up making a profit, or did she face a loss in the end?
Before you jump to conclusions, I encourage you to grab a piece of paper or just mentally note down the transactions as you read along. Sounds easy, right? Well, many find themselves stumped by what initially seems like a simple math problem. Let’s break it down step by step, analyzing each transaction to determine if Anna made a profit or a loss. Ready? Let’s go!
Common Mistakes People Make When Solving This Puzzle
Many people find themselves confused by this puzzle. It’s not because the math is inherently complex but because the sequence of transactions can be misleading if not analyzed carefully. Here are some of the common mistakes people make:
- Focusing on Total Sales Instead of Net Gain or Loss: Some tend to look at the total amount received and compare it to the total amount spent without considering each transaction separately.
- Ignoring the Sequence of Transactions: Since Anna buys and sells twice, it’s important to look at each step in the sequence. Missing even one step can lead to the wrong answer.
- Misinterpreting Profit and Loss: People often confuse revenue with profit. Just because Anna received more money than the initial cost doesn’t automatically mean she made a profit.
Now that we’ve highlighted the potential pitfalls, let’s dive into the step-by-step analysis of Anna’s transactions to determine whether she actually made a profit or loss.
Step-by-Step Solution: Analyzing Anna’s Transactions
Step 1: Initial Purchase
Anna bought the cow for $100. This is the first expense in the series of transactions. At this point, she is down by $100.
- Total Balance: -$100
Step 2: First Sale
Anna then sold the cow for $120. This is a profit compared to her initial purchase. She makes $20 more than what she initially paid.
- Calculation: $120 (revenue) – $100 (cost) = +$20
- Total Balance: +$20
At this stage, Anna has made a net profit of $20. However, she hasn’t completed all the transactions yet.
Step 3: Buying the Cow Back
Anna bought the cow back for $150. This is another expense, which means her balance will decrease.
- Calculation: -$150 (buying back)
- Total Balance: +$20 (previous balance) – $150 = -$130
At this point, Anna’s total balance shows a loss of $130 after buying the cow back. This step is crucial because it significantly affects her overall profit and loss calculation.
Step 4: Final Sale
Finally, Anna sold the cow for $170. This brings in additional revenue, and we need to add this to her existing balance.
- Calculation: +$170 (final sale)
- Total Balance: -$130 (previous balance) + $170 = +$40
After the final transaction, Anna’s total balance is +$40. This means that she made a profit of $40 from all these transactions combined.
Conclusion: Anna Made a Profit of $40
So, there you have it! Anna did, in fact, make a profit, and it amounts to $40. Despite the back-and-forth nature of the transactions, her overall financial position improved. This example clearly shows the importance of breaking down each transaction separately and calculating the balance step by step.
