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 Tara who likes Blue.
- Ira sits opposite Mira on the grid edges.
- Sahil is at a corner and does not like Brown.
- Priya is adjacent to Qadir.
Question: In a 3x3 grid (rows and columns numbered 1 to 3), who occupies the cell at row 1, column 2?
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
--- | --- | ---
Sahil/Green | Mira/Brown | Qadir/Purple
Nihal/Pink | Tara/Blue | Priya/Yellow
Fatima/White | Ira/Red | Hina/Orange
Verification:
- Center, opposite, and corner constraints satisfied.
- Adjacency satisfied by orthogonal neighbors.
- Each person/color used exactly once.
