Reasoning – Input Output
What is Input Output?
You’re given an initial input (numbers or words) and a sequence of steps modifying it. Identify the rule or predict the next step/output.
Types of Patterns
1. Alphabetical/Dictionary sorting
2. Numeric ascending/descending
3. Shifting elements left/right
4. Interleaving or alternate movement
Example Questions
- Input: 54 28 13 99
Step 1: 13 54 28 99
Step 2: 13 28 54 99
What is the logic?
Answer: Answer: Ascending arrangement from left.
- Input: mango apple cherry banana
Step 1: apple banana cherry mango
Step 2: banana cherry mango apple
Answer: Answer: Rotational movement
Exam Tips
- Track position change across each step.
- Focus on what’s fixed vs moved in each transition.
- Test rules like sorting, swapping, or cyclic shifts.
Common Mistakes
- Jumping to conclusions before checking multiple steps.
- Confusing alternating patterns with sorting.
- Not labeling step numbers or outputs clearly.
Quick Revision Checklist
- Practice identifying rules across 4–5 steps.
- Use pencil to reorder elements manually.
- Create mock sequences for practice.
Summary: Input Output questions test pattern recognition over steps. Clarity and consistency in tracking logic ensures accuracy.
