Question 1
Nine distinct persons are arranged in a 3x3 matrix; each cell has exactly one person with a unique color.
- The center cell is occupied by Laksh who likes Pink.
- Nihal sits opposite Diya on the grid edges.
- Vihaan is at a corner and does not like Green.
- Sahil is adjacent to Priya.
Question: In a 3x3 grid (rows and columns numbered 1 to 3), who occupies the cell at row 2, column 1?
Matrix/Spreadsheet Strategy
Label the grid with coordinates (r,c). Use definite placement clues (center, corners, opposites, adjacency) first.
Convert verbal relations to coordinate constraints and eliminate inconsistent options.
A consistent placement is:
C1 | C2 | C3
--- | --- | ---
Vihaan/Brown | Diya/Green | Fatima/Red
Sahil/Yellow | Laksh/Pink | Qadir/Purple
Priya/Orange | Nihal/Blue | Cyrus/Black
Verification:
- Center, opposite, and corner constraints satisfied.
- Adjacency satisfied by orthogonal neighbors.
- Each person/color used exactly once.
