Answer:

$\left[\begin{array}{ccc}7&12&5\\6&8&10\\11&4&9\end{array}\right]$ this is the required 3× 3  puzzle whose side will be equal by adding all the digits .

Step-by-step explanation:

Explanation:

3× 3 puzzle whose side will be equal by adding all the digits .

Let us assume that  $\left[\begin{array}{ccc}7&12&5\\6&8&10\\11&4&9\end{array}\right]$   this is our required  3× 3 puzzle .

Now , we  check weather it is correct or not

Step:1

On adding all the  digits of each row and each column  we get ,

$R_1 =$7 + 12 + 5 =24

$R_2$ = 6 + 8 + 10 = 24

$R_3$ = 11 + 4 + 9  = 24

Similarly ,

$C_1$ = 7 + 6 + 11 = 24

$C_2$ = 12 + 8 + 4 = 24

and $C_3$ = 5 + 10 + 9 = 24

Here, we can see that when we add all the digits from each row or  each column, the result is always 24.

Final answer :

Hence , $\left[\begin{array}{ccc}7&12&5\\6&8&10\\11&4&9\end{array}\right]$ this is a 3× 3 puzzle whose side will be equal by adding all the digits .
