Answer 1

Answer:

ii) is a magic square.

You can verify this by checking the sum in each row.

i.e.

1-10+0 = -4-3-2 = -6+4-7 = -9

Similarly the sum of each column:-

1-4-6 = -10-3+4 = 0-2-7 = -9

and the sum in in each diagonal is:-

1-3-7 = 0-3-6 = -9

Hence the sum is -9 every time .

Thus it is a magic square
