Question 3

A word is represented by only one set of number is given in any one of the alternatives. The sets of number given in the alternatives are represented by two classes of alphabets as in two matrices given below. The column 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; S can be represented by 02,32,etc and N can be represented by 00,42,etc,similarly,you have to identify the set for the word SNAG
MATRIX I
