Seven boxes A, B, C, D, E, F and G are kept one over the other but not necessarily in the same order. Only four boxes are kept between C and A. Only six boxes are kept below D. E is kept below G but above C. B is below F but above G. How many boxes are kept above G?

Explanation

• The clue "Only six boxes are kept below D" fixes D's position at the top (position 7) of the seven-box stack.
• The clues "E is kept below G but above C" (G > E > C) and "B is below F but above G" (F > B > G) combine to form a single mandatory sequence: F > B > G > E > C.
• The clue "Only four boxes are kept between C and A" means they must occupy positions 1 and 6.
• To accommodate the five-box sequence (F > B > G > E > C), C must be at the bottom (position 1), which places A at position 6.
• This results in the final order (top to bottom): D, A, F, B, G, E, C.
• Counting the boxes above G (at position 3) reveals four boxes: B, F, A, and D.

Why Other Options Were Wrong

• Option A: This is incorrect. Counting the boxes above G in the final arrangement (B, F, A, D) gives a total of four, not three.
• Option B: This is incorrect. There are only four boxes above G. Five boxes would be above the box at position 2.
• Option D: This is incorrect. Six boxes are below D, not above G.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Linear Arrangement as background academic context rather than a clinical decision trigger.
• Logical reasoning questions in nursing exams assess the ability to process multiple pieces of information, identify priorities, and draw accurate conclusions under pressure.
• These skills are directly transferable to clinical practice, such as when a nurse must interpret a patient's symptoms, lab results, and history to determine the most critical intervention.
• What if the clue was 'Only three boxes are kept between C and A'? The arrangement would change significantly, requiring a complete re-evaluation of the box positions, demonstrating the need for careful attention to every detail in a clinical scenario.

How to Approach the Question

• First, identify the most definitive clue to establish an anchor point. Here, 'Only six boxes are kept below D' fixes D's position at the top.
• Next, tackle clues that create large structural constraints. 'Only four boxes are kept between C and A' drastically limits their possible positions to the pair (1, 6).
• Combine smaller, relative positioning clues into a single, longer sequence. (G > E > C) and (F > B > G) merge into (F > B > G > E > C).
• Test the limited possibilities from step 2 against the sequence from step 3 to find the one valid arrangement.
• Once the final order is established, carefully read the question again ('How many boxes are kept above G?') and count to find the answer.
