In a certain code language, if the word "DESK" is written as "EFTL", how is the word "LAMP" written in that code language?

  1. MBNQAnswer
  2. B
    KZLO
  3. C
    NCOR
  4. D
    MBNP

Answer

MBNQ
Each letter in the original word is replaced by its immediate next letter in the English alphabet (+1 positional shift). Shifting the letters of LAMP forward by 1 position gives L → M, A → B, M → N, and P → Q, resulting in MBNQ.

Step-by-Step Solution

1
Analyze the rule used to code DESK into EFTL.
D → E (+1), E → F (+1), S → T (+1), K → L (+1). The pattern is a +1 forward shift for each letter.
Establishing the exact letter transformation rule from the given example.
2
Apply the identified +1 forward shift rule to the target word LAMP.
L → M (+1), A → B (+1), M → N (+1), P → Q (+1).
Executing the rule consistently across all positions in the word LAMP.
