Question

In a 3×3 matrix each row uses three different fillings (blank, hatched, solid). Find the missing cell.

• A. A
• B. B
• C. C
• D. D
• E. E

Hint:

This is a "Latin Square" logic puzzle. Ensure that no filling type repeats in any row OR any column.

Answer 1

The Correct Option is A

Step 1: Analyse options.
- The $3 \times 3$ matrix is defined by a set of three distinct fillings: blank (no filling), hatched (lines), and solid (completely filled). - Each row must contain exactly one of each type of filling. - In the final row, the blank and solid cells are already present; therefore, the missing cell must be the hatched one.
Step 2: Conclusion.
Figure A provides the missing hatched filling. Final Answer: (a) A
