Question

Two matrices are provided: Matrix I uses row and column numbers 0 to 4. Matrix II uses row and column numbers 5 to 9. A letter is represented by row number, column number (for example, 23 means row 2, column 3 in Matrix I; 66 means row 6, column 6 in Matrix II). From the matrices, find the row-column codes for each letter in DUNG in sequence, and select the correct option from the given alternatives.

  4. D. 42, 57, 75, 11 (Correct answer)

Correct Answer

Option D — 42, 57, 75, 11

Detailed Solution & Explanation

The correct answer is 42, 57, 75, 11.

Key Points

  • Each code is read as row digit followed by column digit, with Matrix-I indexed 0-4 and Matrix-II indexed 5-9.
  • Decode the keyed option letter by letter:
    • 42 — Matrix-I, row 4, column 2 → D
    • 57 — Matrix-II, row 5, column 7 → U
    • 75 — Matrix-II, row 7, column 5 → N
    • 11 — Matrix-I, row 1, column 1 → G
  • Read in sequence that gives D-U-N-G, exactly the required word.

Additional Information

  • The two matrices never share an index range, so the first digit alone tells you which grid to look in — 0-4 means Matrix-I and 5-9 means Matrix-II. Checking that first halves the search.
  • Most letters appear in more than one cell, so several valid codes exist for the same word; the question asks only for the option that decodes correctly, not for the unique code.
  • Work in the order given — decoding the four codes but assembling them out of sequence is the commonest error.
  • Verifying a single position is often enough to eliminate an option, so test the first code of each and discard those that fail before decoding the rest.
