A word is represented by only one set of numbers as given in any one of the alternatives . The sets of numbes 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 P can be represented by 22, 75 etc, and L can be represented by 20 , 78 etc . Similarly you have to indentify the set for the word WATCH .

In each of the following questions, 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. 'E' can be represented by 01, 13, etc. and 'L' can be represented by 56, 77 etc. Similarly, you have to identify the set for the word given in each question.
