Question

Find the value of magic square.

Answer 1

The Concept of Solving a Magic Square is that the sum of all numbers in each $row,column$ and $diagonal$ are $equal$ to $15$

Now,

$7$	let $x$	$17$
let $y$	$5$	let $z$
let $a$	let $b$	let $c$

Now, in first row

$Sum=7+x+17=15\Rightarrow x=-9$

Now in second column

$Sum=-9+5+b=15\Rightarrow b=19$

Now in first Diagonal

$Sum=7+5+c=15\Rightarrow c=3$

Now in Second Diagonal

$Sum=17+5+a=15\Rightarrow a=-7$

Now in first column

$Sum=7+y-7=15\Rightarrow y=15$

Now in third column

$Sum=17+z+3=15\Rightarrow z=-5$

Therfore Required magic Square is

$7$	$-9$	$17$
$15$	$5$	$-5$
$-7$	$19$	$3$
