Five men A, B, C, D, E read a newspaper one after another. The first reader passes it to C (so C reads second). The last reader received it from A (so A reads just before last). E is neither first nor last. There are exactly two readers between B and A. Who read last?
-
AE
-
BB
-
CD
-
DA
Answer
Correct Answer: D
Explanation
Introduction / Context:This is an order-ranking puzzle. Careful translation of each sentence into positional constraints allows a unique sequence of five readers.
Given Data / Assumptions:
- Readers are in order positions 1 through 5.
- “First gives it to C” ⇒ C is position 2.
- “Last had taken it from A” ⇒ A is position 4, and position 5 is the last reader.
- E is neither first nor last ⇒ E ∈ {2,3,4} but 2 and 4 are already taken by C and A; thus E is position 3.
- Exactly two readers between B and A ⇒ With A at position 4, B must be position 1.
Concept / Approach:Fill the fixed slots first (C second, A fourth), then apply exclusions (E not first/last) and the gap rule (two between B and A) to place B and E. The remaining person automatically becomes the last reader.
Step-by-Step Solution:
Place C at 2; A at 4.E cannot be 1 or 5 ⇒ E at 3.Two readers between B and A (A at 4) ⇒ B at 1.Remaining person (D) must be at 5 (last).Verification / Alternative check:Sequence is B (1) → C (2) → E (3) → A (4) → D (5). All clues satisfied.
Why Other Options Are Wrong:E cannot be last; A is penultimate by statement; B is first by the gap rule.
Common Pitfalls:Misplacing the “two between B and A,” or forgetting that C must be second.
Final Answer:D
