Inequality • Direct and coded inequalities
Inequality: Full-Length Notes (Direct and Coded Inequalities with Examples) 1. Introduction Inequality reasoning is a core topic in competitive exams, testing your ability to deduce relationships between variables using mathematical or coded symbols. Questions are typically of two types: Direct Inequality : Uses standard symbols (<, >, =, ≤, ≥). Coded Inequality : Uses new or coded symbols to represent the above relations, which must be decoded before solving 1 2 3 . 2. Direct Inequality A. Symbols and Meanings > : Greater than < : Less than = : Equal to ≥ : Greater than or equal to ≤ : Less than or equal to ≠ : Not equal to B. How to Approach Direct Inequality Questions Combine Statements Using Common Terms If A > B and B > C, then A > C. If A ≥ B and B = C, then A ≥ C. Undefined Relations If statements have no common term (e.g., A > B and C > D), the relation between A and D is undefined 2 . Complementary Pairs Only...
