Common Mistakes When Solving This Problem
If you answered 5000, you’re not alone. This is one of the most common errors. Many people quickly add up the numbers in their head and overlook a key detail. The issue often arises due to a misstep in mentally adding the numbers. The series of 1000s can throw off your calculation, and it’s easy to add incorrectly when juggling the different sums mentally.
Another common reason for the mistake is the rhythm of adding round numbers like 1000 and 100. People tend to speed up, which leads to overestimation. But as you’ll soon see, the correct answer is not 5000.
Breaking Down the Correct Answer Step by Step
Let’s walk through the problem step by step and ensure everything is crystal clear.
Start with 1000:
- Total = 1000
Add 40:
- Total = 1040
Add 1000:
- Total = 2040
Add 30:
- Total = 2070
Add 1000 again:
- Total = 3070
Add 20:
- Total = 3090
Add 1000 once more:
- Total = 4090
Finally, add 10:
- Final Total = 4100
The correct result is 4100.
Why Is This Challenge Tricky?
The simplicity of the problem can be misleading. The repetition of adding 1000 multiple times can make it easy to lose track of where you are in your mental tally. Additionally, our brains are wired to make quick assumptions, so we tend to rush to an answer without thoroughly double-checking each step. This is why many people jump to the answer 5000 instead of correctly calculating 4100.
