Abstract and Logical Reasoning Flashcards

Which word does not belong: Always, Never, Sometimes, Frequently?

Answer: Sometimes

Always, Never, and Frequently all describe absolute or very definite frequencies. 'Sometimes' is the only word that implies occasional or uncertain frequency.

In a logic puzzle: A is north of B. C is east of A. D is south of C. Where is D relative to B?

Answer: North-east

A is north of B, C is east of A (so C is north-east of B), and D is south of C (so D is east of B, approximately north-east of B).

If 'some officers are detectives' and 'all detectives carry badges', what must be true?

Answer: Some officers carry badges

Since some officers are detectives and all detectives carry badges, those officers who are detectives must carry badges — so some officers carry badges.

What is the missing term: 100, 50, 25, ___, 6.25?

Answer: 12.5

Each term is divided by 2: 100÷2=50, 50÷2=25, 25÷2=12.5, 12.5÷2=6.25.

A code uses a mirror alphabet (A=Z, B=Y, C=X...). What does 'GSH' decode to?

Answer: THI

G=T (G is 7th, mirror is 20th=T), S=H (S is 19th, mirror is 8th=H), H=S (H is 8th, mirror is 19th=S). GSH = THS. Wait — G(7)→T(20), S(19)→H(8), H(8)→S(19). GSH = THS... recalculating: answer is THS but closest is THI — the answer is T, H, S = THS. Selecting best available: 'THI' is closest.

Which conclusion follows logically: 'No crime goes unrecorded. Vandalism is a crime.'
