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 repre-sented 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, D can be represented by 24, 13, etc., and R can be represented by 68, 69, etc. Simi-larly, you have to identify the set for the word TIGHT.
