Brain Test Level 122 Walkthrough: How many minutes for one bird?
Complete Solution, Step-by-Step Explanation, Common Mistakes
🧩 Level Information
- Level Number: 122
- Question: "5 birds take 5 minutes," but it doesn't say "1 bird takes 5 minutes." Enter a number.
- Difficulty: normal
🎯 Objective
Read the conditions carefully and realize that the time does not change for one bird, and enter "5".
📝 Steps to Solve
- Read the question carefully. Note that it doesn't say "1 bird takes 5 minutes."
- The expression "5 birds take 5 minutes" means it takes 5 minutes even if 5 birds work together, not "1 minute per bird."
- Therefore, regardless of the number of birds, the time required for the task itself is interpreted as 5 minutes.
- Realize that even if asked "How many minutes for one bird?" the answer remains the same at 5 minutes.
- Enter "5" in the answer input field to confirm.
💡 Hints
- First, try reading the question text slowly. Does it say "1 bird takes..."?
- Check if you're mistakenly assuming "5 birds take 5 minutes" means "1 minute per bird."
- Consider that the time required for the task is the same even if the number of birds changes; what would the time be?
- Instead of trying to divide in calculations, carefully consider the numbers as they are.
🧠 Explanation & Key Points
This puzzle is a trick question that exploits the tendency to rush into ratio calculations from the condition "5 birds take 5 minutes," mistakenly thinking "1 bird would take 1 minute," "5 x 1 = 5 birds, so 1 minute." In reality, the phrase "5 birds take 5 minutes" means "even if 5 birds work together, it takes 5 minutes for the task to complete," and it does not specify "time per bird." Therefore, the correct interpretation is that it takes 5 minutes to complete the task even with one bird. This is a typical trick question that requires the ability to accurately understand the conditions in the text rather than performing calculations.
🔍 Common Mistakes
- Thinking "5 birds take 5 minutes, so 1 bird would take 1 minute" and entering "1".
- Creating an imaginary ratio like "1 bird takes 5 x 5 = 25 minutes?"
- Avoiding the visibly apparent number "5" from "5 birds" and looking for a different number.
- Skipping over the nuance "it doesn't say 1 bird takes 5 minutes" and assuming it's a normal calculation problem.
🎉 Advice After Clearing
Congratulations if you noticed that it doesn't say "1 bird takes 5 minutes." This stage makes you realize the importance of reading the textual conditions straightforwardly. In the next level, continue to focus on "reading carefully" before calculating.
