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. `W_21`
B. `U_12`
C. `X_12`
D. `Z_21`

Answer

D

Explanation

Put A =1, B 2, C = 3, ...... X = 24, Y =25, Z = 26
The pattern is as follows:
In the first column, B+ I = 2 + 9 = 11 = K,
In the second column, E + L = 5 + 12 = 17 = Q and In the third column, D + V = 4 + 22 =26=Z
The numbers are arranged as follows
In the first row, `7^2 - 1^2 = 48,`
In the second row, `4^2-3^2 = 7` and
In the third row, `5^2-2^2 =21 `
Therefore, Missing pair of letter and number ` = Z_21`
