Complete Analysis and Step-by-Step Solutions
1: What is 8 x 7?
- Solution: 56.
- In-Depth Analysis: This basic arithmetic problem is not as simple as it seems. For many, even basic numbers can be tricky when mental math isn’t second nature. The key here is reinforcing multiplication table memory. These types of calculations aren’t just useful in math but also enhance practical skills like quick estimation.
- Takeaway: Practicing mental math strengthens agility, which is crucial for tasks requiring speed and precision.
2: Apples
- Solution: 3.
- In-Depth Analysis: This riddle doesn’t test math skills but rather interpretive logic. It plays with the concept of possession: even if you give one apple away, you still “have” the remaining apples in your hands.
- Takeaway: This exercise enhances attention to detail and contextual understanding, essential for tackling non-linear problems.
3: Capital of Italy
- Solution: Rome.
- In-Depth Analysis: This general knowledge question evaluates memory and association skills. Recognizing the relationship between countries and capitals measures not only information retention but also how quickly you can access that knowledge.
- Takeaway: Remembering basic facts strengthens your ability to make quick connections, useful in strategic decision-making and data analysis.
4: Number Sequence (2, 4, 8, 16…)
- Solution: 32.
- In-Depth Analysis: The key here is recognizing that each number is double the previous one. Spotting logical patterns is a fundamental skill in mathematics, programming, and data analysis.
- Takeaway: Recognizing progressions sharpens problem-solving abilities and helps in making data-driven decisions.

5: Who Is the Youngest?
- Solution: Pedro.
- In-Depth Analysis: This exercise tests hierarchical reasoning. Understanding the relationships between ages requires building a mental line and following it step by step.
- Takeaway: Exercises like this improve your ability to organize information and work with complex relationships.
6: Number Sequence (3, 6, 9, 12…)
- Solution: 15.
- In-Depth Analysis: This riddle uses arithmetic progressions, where each number increases by a constant value. Here, 3 is added to each number. Identifying this pattern strengthens basic mathematical skills and prepares the mind for more complex calculations.
- Takeaway: Mastering number sequences aids in predictive analysis and financial modeling.
7: Chemical Symbol (Au)
- Solution: Gold.
- In-Depth Analysis: This tests associative memory and scientific knowledge. “Au” derives from the Latin word “aurum,” requiring not just recall but also an understanding of etymology and chemistry.
- Takeaway: Recognizing symbols is essential in technical fields like chemistry, where errors can be costly.
8: Train Travel Time
- Solution: 2 hours.
- In-Depth Analysis: This problem uses a simple physics formula: T=D/VT=D/V. Translating words into numbers and understanding the relationship between speed, distance, and time is key here.
- Takeaway: Applying formulas to practical problems enhances decision-making in complex situations.
9: Triangle with a 90° Angle
- Solution: Right triangle.
- In-Depth Analysis: This tests basic geometry knowledge and reinforces the importance of identifying specific properties in mathematical shapes.
- Takeaway: Mastering fundamental geometry concepts is vital in engineering, design, and technical disciplines.
10: Painted Cubes
- Solution: 6 cubes.
- In-Depth Analysis: Visualizing a large cube divided into 27 smaller parts requires spatial reasoning. The cubes with three painted faces are located at the corners of the larger cube. This riddle demands three-dimensional reasoning and abstraction.
- Takeaway: Spatial visualization is critical in architecture, design, and programming.
