Question

In the following question, a matrix of certain characters is given. These characters follow a certain trend, row-wise or column-wise. Find out this trend and choose the missing character accordingly.

$1$	$7$	$9$
$2$	$14$	$?$
$3$	$105$	$117$

• A. $26$
• B. $20$
• C. $16$
• D. $12$

Answer 1

The correct option is D $12$

By checking the elements of the matrix

$1\times 2+1=3$

$7\times 14+7=105$

Let the unknown number be 'x'

$9x+9=117\Rightarrow 9x=108$

Hence $x=\frac{108}{9}=12$
