If all Bloops are Razzies, and all Razzies are Lazzies, which of the following must be true?
Answer: All Bloops are Lazzies
By transitivity: if Bloops ⊆ Razzies and Razzies ⊆ Lazzies, then Bloops ⊆ Lazzies.
What number comes next in the sequence: 3, 6, 12, 24, 48, ?
Answer: 96
Each term is doubled: 3×2=6, 6×2=12, 12×2=24, 24×2=48, 48×2=96.
In a logic puzzle, P implies Q, and Q implies R. If R is false, what can be concluded?
Answer: P is false
By contrapositive: if R is false, then Q is false (since Q→R); if Q is false, then P is false (since P→Q).
Four employees — Alice, Bob, Carol, and Dan — sit in a row. Alice is not next to Bob. Carol sits at one end. Dan sits next to Alice. Who can sit at the other end?
Answer: Bob
With Carol at one end and Dan next to Alice, placing Bob at the other end satisfies the constraint that Alice is not next to Bob.
Which of the following is logically equivalent to 'If it rains, the ground is wet'?
Answer: If the ground is not wet, it did not rain
The contrapositive of 'If P then Q' is 'If not Q then not P,' which is logically equivalent to the original statement.
What letter comes next in the sequence: A, C, F, J, O, ?
Answer: U
The gaps between letters increase by 1 each time: +2 (A→C), +3 (C→F), +4 (F→J), +5 (J→O), +6 (O→U).
