In a magic square each row, column and diagonal have the same sum. Check which of

the following is a magic square.

(i)

5	-1	-4
-5	-2	7
0	3	-3

(ii)

1	-10	0
-4	-3	-2
-6	4	-7

From the above question, we have

In the (i) square by adding every row and column we get sum which is equal to 0 but the sum of one of its diagonals is not 0

As,

-4 – 2 = - 6

- 6 0

Similarly,

In the (ii) square by adding every row and column we get sum which is equal to -9. Also all the diagonals of this square gives the same sum ie. -9

Therefore,

It is a magic square
