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 'K' can be represented by 40, 24  etc and 'Z' can be represented by 98, 67 etc.  Similarly, you have to identify the set for the  word 'OXEN'.
