Question 11
Beaver farms are divided into small squares. The centre square is a warehouse, while the other squares are used to grow grass or wheat. Every year the beavers must report to the authorities the number of squares used to grow wheat. The report includes the total number of wheat-growing squares in each row and column, as below.
The original example labels “Cỏ” mean grass and “Lúa” mean wheat. Its editable grid is:
| Grass | Wheat | Grass |
|---|---|---|
| Wheat | Warehouse | Grass |
| Grass | Wheat | Grass |
Row totals: 1,1,1; column totals: 1,2,0.
Which of the following beaver reports is correct?
| Option | Row totals, top to bottom | Column totals, left to right |
|---|---|---|
| A | 3,0,3,2,1 | 3,0,1,1,2 |
| B | 3,2,1,2,4 | 2,2,3,2,3 |
| C | 0,3,3,1,1 | 0,3,3,1,1 |
