CODING AND DECODING MCQs
Coding-Decoding
Directions:
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 are numbered from 0 to 4 and those of Matrix II 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 I & II, 'D' can be represented by 00,14, etc.; 'M' can be represented by 58,67, etc.; Similarly you have to identify the correct set for the word given in each question.
