Question : Directions: 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 in the two matrices, given below. 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, e.g. M can be represented by 01, 10, etc., and A can be represented by 56, 65, etc. Similarly, you have to identify the set for the word ROD.

Correct Answer: 67, 96, 57
Solution :
Given:
ROW
Number representations of each letter –
R→58, 67, 76, 85, 99
O→55, 69, 78, 87, 96
D→57, 66, 75, 89, 98
Let's check the options –
First option:
58, 66, 78; O and W cannot be represented by 66 and 78 respectively.
Second option:
67, 96, 57; All letters of ROW can be represented through this option.
Third option:
56, 66, 86; R, O, and W cannot be represented by 56, 66, 86 respectively.
Fourth option
: 58, 69, 65; W cannot be represented by 65.
So, only the second option consists of the numbers through which ROW can be represented. Hence, the second option is correct.
