Revision Notes — Boolean Logic

Key concepts, formulas, and definitions from Boolean Logic for SNAP Data Interpretation & Logical Reasoning preparation.

Key Topics to Revise

1

Fundamentals of Boolean Logic

  • Boolean Logic reduces all values to either TRUE or FALSE - binary logic system
  • Primary operations in Boolean Logic are AND, OR, and NOT (similar to arithmetic operations)
  • Knights always tell the truth - they cannot claim to be knaves
2

Problem-Solving Strategies

  • Analyze each statement for logical consistency with character types
  • Use contradiction method - if assuming someone is a knight leads to contradiction, they must be a knave
  • For road/direction problems, ask questions that yield same response from both knights and knaves
3

Advanced Problem Types

  • Language barrier problems where 'yes/no' meanings are unknown
  • Alternator characters who switch between truth and lies
  • Multiple question scenarios requiring strategic questioning
