Based on the given matrix, we can add the corresponding elements in each row and write them in the first column. Similarly, we can add the corresponding elements in each column and write them in the last row. The resulting matrix with these values will have the same sum for all rows, columns, and diagonals. For example, adding 1 + 2 + 3 gives us 6, which we write in the first column and likewise, adding 1 + 4 + 7 gives us 12, which we write in the last row. The updated matrix looks like: 6 2 5 8 3 5 2 10 7 8 4 12 16 15 11 12 Now, we can see that the sum of each row, column, and diagonal is 21, which is the same. Therefore, the answer is a) 21.
This seems to be the answer for you.
