This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
NALKNP

Coding Logic Explained

This question involves a simple letter substitution cipher based on the position of letters in the alphabet.

Determining the Pattern

Compare the letters of the original word 'WIRE' with its coded form 'SENA':

  • W (23rd letter) becomes S (19th letter)
  • I (9th letter) becomes E (5th letter)
  • R (18th letter) becomes N (14th letter)
  • E (5th letter) becomes A (1st letter)

The pattern observed is that each letter in the original word is shifted 4 positions backward in the alphabet.

Mathematically, the shift can be represented as: Original Position - 4 = Coded Position.

Applying the Pattern to 'REPORT'

Now, apply the same logic (subtracting 4) to each letter of the word 'REPORT':

  • R (18th letter) - 4 = 14th letter, which is N
  • E (5th letter) - 4 = 1st letter, which is A
  • P (16th letter) - 4 = 12th letter, which is L
  • O (15th letter) - 4 = 11th letter, which is K
  • R (18th letter) - 4 = 14th letter, which is N
  • T (20th letter) - 4 = 16th letter, which is P

Combining these letters gives the coded word: NALKNP.

Conclusion

Therefore, 'REPORT' is coded as 'NALKNP', which matches Option 4.
