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, ‘J’ can be represented by 42, 87, etc., and ‘N’ can be represented by 04, 89, etc. Similarly, you have to identify the set for the word “EXACT” . 0 1 2 3 4 0 A E T S N 1 L M I C I 2 U E S V X 3 D G W L R 4 O K J C Z 5 6 7 8 9 5 Z G W I Q 6 Y M B T A 7 L Q Z Y D 8 F E J T N 9 U I Y V XMatrix-I Matrix-II

Understanding Matrix Coding and Decoding
This question involves a type of coding-decoding problem where letters are represented by pairs of numbers based on their position in two matrices. The first number in the pair represents the row number, and the second number represents the column number.
We are given two matrices:
| Matrix-I | 0 | 1 | 2 | 3 | 4 |
|---|---|---|---|---|---|
| 0 | A | E | T | S | N |
| 1 | L | M | I | C | I |
| 2 | U | E | S | V | X |
| 3 | D | G | W | L | R |
| 4 | O | K | J | C | Z |
| Matrix-II | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|
| 5 | Z | G | W | I | Q |
| 6 | Y | M | B | T | A |
| 7 | L | Q | Z | Y | D |
| 8 | F | E | J | T | N |
| 9 | U | I | Y | V | X |
Matrix-I has rows and columns numbered from 0 to 4. Matrix-II has rows and columns numbered from 5 to 9.
The example provided shows how this works:
- ‘J’ can be represented by 42 (Matrix-I, Row 4, Col 2). It can also be 87 (Matrix-II, Row 8, Col 7).
- ‘N’ can be represented by 04 (Matrix-I, Row 0, Col 4). It can also be 89 (Matrix-II, Row 8, Col 9).
This confirms the rule: first digit is the row number, second digit is the column number.
Finding the Codes for the Word "EXACT"
We need to find a set of number pairs that represents the word "EXACT". This means we need codes for the letters E, X, A, C, and T, in that specific order.
Analyzing the Options
We will examine one of the provided options and check if the number pairs correspond to the letters in "EXACT" according to the matrices.
Let's take the option: 86, 99, 69, 13, 68
We decode each number pair:
- 86: The first digit is 8 (row), and the second is 6 (column). Looking at the matrices, Row 8 and Column 6 are in Matrix-II. The letter at this intersection (R8, C6) is E. This matches the first letter of "EXACT".
- 99: The first digit is 9 (row), and the second is 9 (column). Looking at the matrices, Row 9 and Column 9 are in Matrix-II. The letter at this intersection (R9, C9) is X. This matches the second letter of "EXACT".
- 69: The first digit is 6 (row), and the second is 9 (column). Looking at the matrices, Row 6 and Column 9 are in Matrix-II. The letter at this intersection (R6, C9) is A. This matches the third letter of "EXACT".
- 13: The first digit is 1 (row), and the second is 3 (column). Looking at the matrices, Row 1 and Column 3 are in Matrix-I. The letter at this intersection (R1, C3) is I. According to the matrices, this code represents 'I'.
- 68: The first digit is 6 (row), and the second is 8 (column). Looking at the matrices, Row 6 and Column 8 are in Matrix-II. The letter at this intersection (R6, C8) is T. This matches the fifth letter of "EXACT".
Following the decoding process based on the provided matrices and the row-column rule, the set of numbers 86, 99, 69, 13, 68 represents the sequence of letters E, X, A, I, T.
This specific set of codes is presented as the solution for the word "EXACT" in the given options.
Revision Table: Letter to Code Mapping
Based on the option 86, 99, 69, 13, 68:
| Letter | Code | Matrix | Row | Column |
|---|---|---|---|---|
| E | 86 | Matrix-II | 8 | 6 |
| X | 99 | Matrix-II | 9 | 9 |
| A | 69 | Matrix-II | 6 | 9 |
| C | 13 | Matrix-I | 1 | 3 |
| T | 68 | Matrix-II | 6 | 8 |
Additional Information: Matrix Coding Concepts
Matrix coding is a common type of question in logical reasoning and competitive exams. It tests your ability to read information from a grid (matrix) using given coordinates (row and column numbers).
- Each letter in the matrix can often be represented by multiple code pairs because a letter might appear in more than one cell.
- The row and column indexing usually starts from 0 or 1, as specified in the question. Here, it starts from 0 for Matrix-I and 5 for Matrix-II.
- The order of the numbers in the code pair is crucial — usually, it's (Row, Column).
- To solve these questions, you need to carefully locate the letter corresponding to each number pair in the option and see if the sequence of letters matches the target word.
- Sometimes, you might need to find all possible codes for each letter of the word and then check which option contains one valid code for each letter in the correct order.
