Syllogism — Study Notes
Overview
Syllogism is a fundamental reasoning topic in the UP Police Constable exam where you must draw logical conclusions from given statements involving categorical propositions using terms like "All", "Some", "No" and "Some not". This topic tests your ability to think logically without relying on general knowledge or real-world truth — you must accept the given statements as true even if they contradict reality (e.g., "All dogs are cats" must be treated as true within the question context).
Syllogism questions typically provide two or three statements followed by multiple conclusions, and you must determine which conclusions logically follow from the statements. Mastery of Venn diagrams, basic distribution rules, and possibility cases is essential. This topic appears regularly with 3–5 questions in the reasoning section. Students who learn the systematic approach using Venn diagrams can solve these questions accurately within 30–45 seconds each.
The key challenge is avoiding assumptions based on real-world knowledge and strictly following logical rules. Most errors occur when students apply common sense rather than formal logic, or when they fail to consider all possible Venn diagram representations of a statement.
