Concept Overview
Input-Output questions present a machine or arrangement that changes words or numbers step by step according to a hidden rule. The task is to identify the rule and predict a required intermediate or final step.
SSC CGL focus: Compare consecutive steps and identify exactly which element moves or changes at each stage.
Quick Tricks & Shortcuts
- Compare Step I with the input before analysing later steps.
- Check whether ordering is ascending, descending, alphabetical, positional, or alternating.
- Once the rule is found, verify it against at least two consecutive steps.
