Direction: Study the two matrices given below. In each question identify the correct number combination for the given word. 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 resented 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 a 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, for example, ‘F’ can be represented by 31, 43 etc., and ‘N’ can be represented by 02, 21 etc. MATRIX I 0 1 2 3 4 0 F A N O I 1 1 O F A N 2 A N O I F 3 O F I N A 4 N I A F O MATRIX II 5 6 7 8 9 5 S E H B T 6 H S E T B 7 B T S E H 8 E H T B S 9 T S E H B

Understanding Matrix Coding for Words
This problem involves decoding a word using two matrices, Matrix-I and Matrix-II. Each letter is represented by a pair of numbers. The first number indicates the row number, and the second number indicates the column number where the letter is located in the matrices.
Matrix-I covers rows and columns from 0 to 4, while Matrix-II covers rows and columns from 5 to 9.
Analyzing the Given Matrices
| MATRIX I | 0 | 1 | 2 | 3 | 4 |
|---|---|---|---|---|---|
| 0 | F | A | N | O | I |
| 1 | O | F | A | N | I |
| 2 | A | N | O | I | F |
| 3 | O | F | I | N | A |
| 4 | N | I | A | F | O |
| MATRIX II | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|
| 5 | S | E | H | B | T |
| 6 | H | S | E | T | B |
| 7 | B | T | S | E | H |
| 8 | E | H | T | B | S |
| 9 | T | S | E | H | B |
The rule for encoding is row number followed by column number. For example, 'F' can be 31 (row 3, column 1) or 43 (row 4, column 3). 'N' can be 02 (row 0, column 2) or 21 (row 2, column 1).
Finding the Code for the Word NEST
We need to find the numerical representation for each letter in the word NEST using the given matrices.
- N: Look for 'N' in Matrix-I. Examples of codes for 'N' are 02, 13, 21, 33, 40.
- E: Look for 'E' in Matrix-II. Examples of codes for 'E' are 56, 67, 78, 85, 97.
- S: Look for 'S' in Matrix-II. Examples of codes for 'S' are 55, 66, 77, 88, 96.
- T: Look for 'T' in Matrix-II. Examples of codes for 'T' are 59, 68, 76, 87, 95.
Checking the Options
Let's examine the first option: 02, 56, 55, 59.
- For the letter N: Check code 02. In Matrix-I, row 0, column 2 is 'N'. This matches.
- For the letter E: Check code 56. In Matrix-II, row 5, column 6 is 'E'. This matches.
- For the letter S: Check code 55. In Matrix-II, row 5, column 5 is 'S'. This matches.
- For the letter T: Check code 59. In Matrix-II, row 5, column 9 is 'T'. This matches.
Since each number pair in the first option correctly represents the corresponding letter in the word NEST according to the matrices, this option is the correct code for NEST.
Important Questions from Matrix
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 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 from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example, ‘E’ can be represented by 32, 12 etc and ‘X’ can be represented by 87, 79 etc. Similarly, you have to identify the set for the word ‘MYTH’.

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 two matrices given below. The columns 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., ‘M’ can be represented by 01, 14, etc., and ‘S’ can be represented by 58, 77 etc., and ‘S’ can be represented by 58, 77 etc. Similarly, you have to identify the set for the word ‘ROHAN’.

A word is represented by only one set of number as given in any one of the alternatives. 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 form 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example ‘U’ can be represented by 30, 41 etc and ‘E’ can be represented by 85, 67 etc. Similarly, you have to identify the set for the word ‘SWORD’.
