Input-Output: Full-Length Notes Focus: Machine-Based Pattern Questions **1. Introduction to Input-Output Reasoning Input-Output questions are a staple in competitive exams’ reasoning sections. They simulate a “machine” that processes an initial input (often a sequence of numbers, words, or both) through a series of steps, following a specific pattern or rule. Your task is to deduce the pattern and answer questions about intermediate or final steps. 2. Types of Input-Output Patterns Number Series: Only numbers are rearranged. Word Series: Only words/letters are rearranged. Mixed Series: Both numbers and words are rearranged. Operation-Based: Mathematical operations (e.g., add/subtract/multiply). Position-Based: Rearrangement by position (e.g., largest to smallest, alphabetical order). Complex/Hybrid Patterns: Multiple rules applied together (e.g., alternate steps for numbers and words). 3.
