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 Uma who likes White.
- Zoya sits opposite Aarav on the grid edges.
- Mira is at a corner and does not like Blue.
- Omar is adjacent to Uma.
Question: In a 3x3 grid (rows and columns numbered 1 to 3), who occupies the cell at row 3, column 3?
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
--- | --- | ---
Mira/Yellow | Zoya/Orange | Vihaan/Pink
Priya/Red | Uma/White | Omar/Black
Fatima/Brown | Aarav/Blue | Rhea/Green
Verification:
- Center, opposite, and corner constraints satisfied.
- Adjacency satisfied by orthogonal neighbors.
- Each person/color used exactly once.
