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 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 42, 31. etc. and 'P' can be represented by 95, 88 etc. Similarly, you have to identify the set for the word given 'ROST'.

56, 44, 67, 40
97, 21, 66, 29
75, 00, 10, 92
68, 33, 65, 58

Correct Answer: 68, 33, 65, 58

Explanation:

From above given matrices I and II , we get different values for word ROST -
R ⇒ 97, 89, 75, 68, 56
O ⇒ 44, 33, 21, 12, 00
S ⇒ 98, 86, 77, 65, 59
T ⇒ 99, 85, 76, 67, 58
From given matrix it is clear that all the values for word ROST are matched in only option ( 4 ) for every letter . So , the set for the word ROST will be 68, 33, 65, 58 .From matrix , option ( 4 ) is correct .
