Reasoning – Arithmetical Reasoning
What is Arithmetical Reasoning?
This involves solving real-life mathematical problems described in words. It combines numerical aptitude with logical reasoning.
Common Types of Questions
1. Profit & Loss, Time-Speed-Distance
2. Ratio-Proportion, Averages
3. Age Problems, Work & Wages
4. Number Puzzles and Patterns
Example Questions
- A train travels 60 km in 1 hour. How far will it go in 2.5 hours?
Answer: 150 km
- If a man can do a job in 10 days, how many men can finish it in 2 days?
Answer: 5 men
- The average of 4, 6, 8, 10 is?
Answer: 7
Exam Tips
- Translate the statement into equations before solving.
- Highlight key numbers and units (e.g., km/hr, Rs, %).
- Break down multi-part questions into manageable steps.
- Use shortcuts where applicable (e.g., speed-distance triangle).
Common Mistakes
- Ignoring unit conversions.
- Rushing into solving without proper understanding of question.
- Skipping steps and miscalculating intermediate values.
Quick Revision Checklist
- Brush up basic formulas in arithmetic.
- Work on speed-math techniques for large numbers.
- Solve word problems from each category.
- Check each step and result in word problems.
Summary: Arithmetical Reasoning enhances your ability to apply math concepts in real-world formats. Structured problem-solving and conceptual clarity are key to accuracy.
