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 42, 34 etc and 'Z'  can be represented by 87, 78 etc. Similarly, you have to  identify the set for the word 'REAL'.
