Question

Check in the following square whether in this square the sum of the numbers in each row and in each column and along the diagonal is the same ???

Answer 1

Answer:

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.

= (12+1+8)/13

= 21/13

4) sum of the numbers in

= (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

= (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.
