Each of the following questions has a Magical matrix with question mark/s. Replace the question mark/s by choosing the correct response from amongst the alternatives given.

Options

A. 10
B. 12
C. 9
D. 15

Answer

D

Explanation

The pattern is as follows
In the first column, `(5 + 8 + 7)/(4) = 5`
In the second column, `(9+6+13)/(4) = 7`
In the fourth column, `(7 + 10 +19 )/(4) = 9`
Let the missing number be x. then, `(8+9+x)/(4) = 8 or x = 15`
Therefore, in the column, missing number = 15
