Did you manage to figure it out?
The correct answer is $20!
Surprised? Let’s break it down step by step to understand why.
Step 1: The First Purchase
The man originally buys the goat for $60.
This means he spends:
−$60
At this point, he owns the goat but hasn’t made any profit.
Step 2: The First Sale
He sells the goat for $70.
Since he originally paid $60, his profit from the first transaction is:
$70 − $60 = $10
He makes a $10 profit on the first sale.
Step 3: He Buys the Goat Again
Next, the man buys the same goat back for $80.
Some people get confused here because the new purchase price is $10 higher than his previous selling price.
However, this is simply the beginning of a second transaction.
He spends $80 to purchase the goat again.
Step 4: The Second Sale
Finally, he sells the goat for $90.
Since he paid $80 for it, his profit on the second transaction is:
$90 − $80 = $10
He makes another $10 profit.
Step 5: Calculate the Total Profit
Now we simply add the profits from both transactions.
First sale: $10 profit
Second sale: $10 profit
$10 + $10 = $20
We can also calculate the result by adding all the money he received and subtracting everything he spent.
Total money received:
$70 + $90 = $160
Total money spent:
$60 + $80 = $140
Total profit:
$160 − $140 = $20
Final Answer: $20!
That’s right! The man made a total profit of $20 from buying and selling the goat twice.
The important thing to remember is that these are two separate transactions, each producing a $10 profit.
The fact that he bought the goat back for a higher price doesn’t cancel out the profit he already made.
