সাতটি বাক্স, A, B, C, D, E, F এবং G, একটির উপর অন্যটি রাখা আছে কিন্তু একই ক্রমে নাও থাকতে পারে। A উপর থেকে তৃতীয় স্থানে রাখা আছে। A এবং D-এর মধ্যে শুধুমাত্র একটি বাক্স রাখা আছে কিন্তু D সবচেয়ে উপরে রাখা নেই। C এবং D-এর মধ্যে শুধুমাত্র দুটি বাক্স রাখা আছে। B এবং E-এর মধ্যে শুধুমাত্র একটি বাক্স রাখা আছে এবং E, G-এর ঠিক উপরে আছে। উপর থেকে দ্বিতীয় স্থানে কোন বাক্সটি আছে?
C
E
D
G
C
Fix the anchor position (A=3rd) and test the two possibilities for D (D can be 1st or 5th), then place the block (E,G) and C to fulfill the spacing constraints.
Fix the anchor position (A=3rd) and test the two possibilities for D (D can be 1st or 5th), then place the block (E,G) and C to fulfill the spacing constraints.
Define Anchor
A is kept 3rd from the top. Total boxes = 7. (1:?, 2:?, 3:A, 4:?, 5:?, 6:?, 7:?)
Placement of D and C
D is not at top. Only one box between A and D. D must be at position 5 (since 1 is not possible). If D=5, two boxes between C and D means C must be at position 2 (5-3=2). So C is 2nd.
Placement of E, G, and B
E is immediately above G. Only one box between B and E. With positions 1, 4, 6, 7 open, we place E=4, G=5 (Wait: D is 5, adjust logic). Corrected: D is 5, positions are 1, 2(C), 3(A), 4, 5(D), 6, 7. If E=4, G=5 (Collision). Let's re-eval: D must be 5? No, D could be 1 (No, rule says not top). If A=3, D can be 1 or 5. If D=1, violates 'not on top'. Therefore D must be 5. Then C is 2. Positions: 1, 2=C, 3=A, 4, 5=D, 6, 7. E and G are block: E=6, G=7. B=4.
B: E is at position 6, not 2nd. C: D is at position 5, not 2nd. D: G is at position 7, not 2nd.
A is correct because placing A at 3rd, D at 5th, and C at 2nd satisfies all positional constraints including the E-G block and B spacing.
In floor-based puzzles, always use a table to map positions 1-7 immediately and cross-check constraints to eliminate impossible scenarios.
