  • question_answer
    Direction: 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 the two given matrices. The columns and rows of Matrix \[{{I}^{st}}\]are numbered from 0 to 4 and those of Matrix \[I{{I}^{nd}}\]from 5 to 9. A letter from these matrices can be represented first by its row and then the column number e.g., in the matrices for questions 1 to 4, M can be represented by 14, 21, etc; 0 can be represented by 20, 32, etc. Similarly you have to identify the correct set for the word given in each question.
