In the following two questions, given below are the two matrices each containing two classes of letters from the alphabets. The columns and rows of Matrix I are prime numbered and that of Matrix II are composite numbered. Letter from these matrices can be represented first by its row number and next by its column number. e.g. P can be written as 48, 66, 84 etc. In the following questions identify one set of number pairs out of (1), (2), (3) and (4) which represent the given word.
