This Simple Horse Trading Riddle Stumped Thousands—Can You Crack It?

Ever wondered why some problems from the past still stump even the brightest minds today? Here’s a classic IQ test question from 1984 that has left many scratching their heads. Let’s dive in and see if you can solve this seemingly impossible problem.

The Horse Trading Problem Explained

Understanding the Transactions

Let’s break down the transactions step-by-step. The man buys a horse for $60, sells it for $70, buys it back for $80, and sells it again for $90. It might seem confusing at first, but each transaction needs to be considered separately.

First Transaction

• The man buys the horse for $60.
• He sells the horse for $70.

Calculation of Profit

• Purchase: -$60
• Sale: +$70
• Profit from first transaction: $10

Second Transaction

• The man buys the horse back for $80.
• He sells the horse again for $90.

Calculation of Profit

• Purchase: -$80
• Sale: +$90
• Profit from second transaction: $10

Total Profit

Now, let’s add up the profits from both transactions:

• First transaction profit: $10
• Second transaction profit: $10
• Total profit: $20

Common Misconceptions

Many people approach this problem differently and end up with incorrect answers. Let’s explore some common misconceptions.

Confusing Total Transactions with Net Profit

Some might think that buying and selling the horse multiple times complicates the net profit calculation, but it’s crucial to view each transaction independently.

Overlooking Individual Transaction Profits

Others might overlook the profit made in each step and instead try to combine all transactions into a single equation, which leads to confusion.

Breaking Down the Steps

Understanding this problem requires careful attention to each step. Let’s break it down further to ensure clarity.

Step-by-Step Analysis

• Buy for $60 and sell for $70: Profit = $10
• Buy back for $80 and sell for $90: Profit = $10

Combining Profits

Adding these individual profits:

• $10 + $10 = $20

Visualizing the Problem

Sometimes, visual aids can help understand complex problems. Imagine two separate timelines for each transaction. This way, it’s easier to see the profits stacking up.

First Timeline

• Starts at -$60
• Ends at +$10 (profit from $70 sale)

Second Timeline

• Starts at -$80
• Ends at +$10 (profit from $90 sale)
