A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-I are numbered from 0 to 4 and that of Matrix-II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example 'G' can be represented by 20, 43 etc and 'R' can be represented by 97, 78 etc. Similarly, identify the correct set for the word 'MARX'.

Solution & Step-by-step Explanation

Let's find the valid numerical codes (Row, Column) for each letter of the word MARX:
M: Can be represented by: 31

A: Can be represented by: 12, 42

R: Can be represented by: 78, 97

X: Can be represented by: 55, 58, 96, 99

Let's cross-verify the option tracks:

Option A: 34 (C), 67 (Q)... → Incorrect

Option B: 13 (B)... → Incorrect

Option C: 31 (M), 42 (A), 97 (R), 99 (X) → This perfectly matches all four target letters MARX.

Option D: 43 (G)... → Incorrect

Thus, Option C is the correct answer.
