Difficulty: EasyCoding and Decoding

Match each original word in List-I with its correctly coded representation in List-II based on its specific alphabetical coding rule.

  • MINTNJOU
  • COLDBNKC
  • HIGHSTRS
  • PARKKRAP

Answer

'MINT' matches with 'NJOU' (+1 shift), 'COLD' matches with 'BNKC' (-1 shift), 'HIGH' matches with 'STRS' (reverse alphabetical pair), and 'PARK' matches with 'KRAP' (letter reversal).
Each word aligns with its precise logical transformation: 'MINT' undergoes a +1+1 position shift to become 'NJOU', 'COLD' undergoes a −1-1 position shift to become 'BNKC', 'HIGH' uses reverse alphabetical pairing to become 'STRS', and 'PARK' reverses its letter order to become 'KRAP'.

Step-by-Step Solution

1
Determine the coding logic for 'MINT'
Shifting each letter forward by 1 position yields M+1=N, I+1=J, N+1=O, T+1=U, forming 'NJOU'.
Identify the forward position shift rule.
2
Determine the coding logic for 'COLD'
Shifting each letter backward by 1 position yields C-1=B, O-1=N, L-1=K, D-1=C, forming 'BNKC'.
Identify the backward position shift rule.
3
Determine the coding logic for 'HIGH'
Replacing each letter with its opposite position in the alphabet (A↔Z,H↔S,I↔R,G↔TA \leftrightarrow Z, H \leftrightarrow S, I \leftrightarrow R, G \leftrightarrow T) forms 'STRS'.
Identify reverse alphabetical indexing rule.
4
Determine the coding logic for 'PARK'
Reversing the left-to-right letter sequence of 'PARK' forms 'KRAP'.
Identify string reversal logic.
