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 5 to 9. A letter from these matrices can be represented  first by its row and next by its column, for example ‘A’ can be represented by 24, 95 etc. and ‘M’ can be represented by 11,66 etc. Similarly, you have to identify the set of the word “PLEAN”.
