**Arrange these numbers so that we get sum 15 by adding numbers from any direction(row, column, diagonal)**

_2_|_6_|_4_

_1_|_5_|_7_

_3_|_8_|_9_

_1_|_5_|_7_

_3_|_8_|_9_

in number’s ko is tarha arrange karein ke jis taraf se bhi add karein ’15’ answer aaye.

1 5 9

1 6 8

2 4 9

2 5 8

2 6 7

3 4 8

3 5 7

4 5 6

Now in order to make diagonal, rows and columns sum to 15, middle element should be present in atleast 4 sequences.

There is only one numbers which is present in four sequences i.e. 5, so 5 will be the middle element.

Now corner number can be the number which is present in atleast three sequences, numbers present atleast in 3 sequences are 2, 4, 6, 8.

Numbers which are present only in two sequences can not be in corners and middle of the matrix, such numbers are 1, 3, 7, 9.

By using above logic, we can create a matrix easily.

_8_|_3_|_4_

_1_|_5_|_9_

_6_|_7_|_2_

Obviously there will be multiple possible answers by rotating the matrix.
