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

  1. Read the question carefully. Note that it doesn't say "1 bird takes 5 minutes."
  2. The expression "5 birds take 5 minutes" means it takes 5 minutes even if 5 birds work together, not "1 minute per bird."
  3. Therefore, regardless of the number of birds, the time required for the task itself is interpreted as 5 minutes.
  4. Realize that even if asked "How many minutes for one bird?" the answer remains the same at 5 minutes.
  5. 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.
