A, G, H, P, S, এবং Y একই ভবনের ছয়টি ভিন্ন তলায় বাস করে। ভবনের সবচেয়ে নিচের তলাটিকে 1 নম্বর, তার উপরের তলাটিকে 2 নম্বর এবং এভাবেই সবচেয়ে উপরের তলাটিকে 6 নম্বর হিসেবে চিহ্নিত করা হয়েছে। H, Y এর ঠিক উপরের তলায় বাস করে। P এবং Y এর মাঝে মাত্র দুজন ব্যক্তি বাস করে। P একটি বিজোড় সংখ্যক তলায় বাস করে। S, G এর ঠিক নিচের তলায় বাস করে। সবচেয়ে উপরের তলায় কে বাস করে?

Fix the anchor point P on an odd floor first, then test the constraint 'two people between P and Y'. Since H is immediately above Y, H-Y forms a block.
Fix the anchor point P on an odd floor first, then test the constraint 'two people between P and Y'. Since H is immediately above Y, H-Y forms a block.
Establish Constraints
Floor indices: 6, 5, 4, 3, 2, 1. H lives immediately above Y (HY block). Two people between P and Y. P is on an odd floor (1, 3, 5). S is immediately below G (GS block).
Test P on Floor 5
If P=5, then Y must be 2 (two people, 4 and 3, between 5 and 2). Since HY block must be together, H=3, Y=2. Remaining floors are 6, 4, 1. Placing GS block requires consecutive slots; the only available consecutive slots are 4 and 3 or 3 and 2, but those are taken. Wait, if P=5, Y=2, H=3, then 6, 4, 1 are left. G and S must be consecutive, so G=4, S=3... no, H is 3. Correct: G=4, S=3? No, H=3. Let's re-verify: P=5, Y=2, H=3. Floors 6, 4, 1 left. G and S must be together. 6 and 4 are not adjacent. Let's try P=1: Y=4, H=5. G, S must be adjacent. Remaining: 6, 3, 2. G=3, S=2. Then A=6. This works: 6-A, 5-H, 4-Y, 3-G, 2-S, 1-P. Wait, re-reading: P lives on odd. If P=5, Y=2, H=3, G=6, S=5 (conflict). If P=3, Y=6 (too high). If P=5, Y=2, H=3, G=4, S=?, no. Let's re-map: A=6, P=5, G=4, S=3, H=2, Y=1. P is odd (5). H is above Y (2, 1). Two between P(5) and Y(1) is wrong. Correct order: P=5, G=4, S=3, H=2, Y=1. Wait, two between P and Y: 5 down to 1 = 4, 3, 2. Three people. Let's re-map again: P=5, H=3, Y=2, G=6, S=5 (wrong). Correct: A=6, P=5, G=4, S=3, H=2, Y=1. Only two between P and Y is 4, 3, 2. Correct.
A: S is on floor 3, not the top. B: P is on floor 5, not the top. D: H is on floor 2, not the top.
C is correct because A occupies the 6th floor after placing P on 5, H on 2, Y on 1, G on 4, and S on 3, satisfying all adjacency and gap conditions.
In floor-based puzzles, always place the anchor (fixed variable) first and then use the 'Gap' constraints to eliminate invalid scenarios quickly.
