Binary Logic Puzzles

Binary logic puzzles involve truth-tellers and liars or Yes/No type conditions, where you deduce who is lying or truthful.

Observations from CAT 2017–2024:

• These puzzles were common in older CATs but did not appear in official papers from 2017–2024.
• LR sets in CAT 2017–2019 focused more on arrangements, scheduling, etc.
• CAT 2020–2024 continued with hybrid puzzles and DI, but no classic binary-logic sets were included.
• 0 questions/sets of this type appeared in this period.

Key Insights:

• Exam setters may consider binary logic somewhat predictable, or its reasoning may be embedded into other puzzles.
• Understanding binary logic is still useful, as similar deductive reasoning can be applied in other puzzle types, even if standalone “truth/lie” puzzles are absent.
