Question

Check whether in this square the sum of the numbers in each row and in each column and along the diagonals is the same.

Answer 1

Solution :

1 )sum of the numbers in

first row = 6/13 + 13/13 + 2/13

= (6+13+2)/13 = 21/13

2 ) Sum of the numbers in

Second row = 3/13+7/13+11/13

= (3+7+11)/13 = 21/13

3 ) sum of the numbers in

Third row = 12/13+1/13+8/13

= (12+1+8)/13

= 21/13

4) sum of the numbers in

First column = 6/13+3/13+12/13

= (6+3+12)/13 = 21/13

5) sum of the numbers in

Second column =13/13+7/13+1/13

= (13+7+1)/13

= 21/13

6) sum of the numbers in

Third column = 2/13+11/13+8/13

= (2+11+8)/13

= 21/13

7) sum of the numbers in

daigonal = 6/13+7/13+8/13

= (6+7+8)/13

= 21/13

8) sum of the numbers in

Second daigonal =12/13+7/13+2/13

=(12+7+2)/13

= 21/13

Therefore ,

In given square sum of the

in each row and each column

and along the diagonal are

equal.
