Question

29,33,35,36,27,34,32,37,? complete the matrix

Answer 1

We have to complete the given matrix:

$\left[\begin{array}{ccc}29&33&35\\36&27&34\\32&37&?\end{array}\right]$

Let us consider the sum of first row of the matrix,

$29+33+35 =97$

Let us consider the sum of second row of the matrix,

$36+27+34=97$

So, we observe that the sum of each row is 97.

So, the sum of third row of the matrix is also 97.

$32+37+?=97$

So, $?=97-69$

= 28

So, the complete matrix is:

$\left[\begin{array}{ccc}29&33&35\\36&27&34\\32&37&28\end{array}\right]$
