Question

In a certain code language, MIRROR is written as NRILI. How will MOBILE be written as in that language?

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

Decoding MOBILE

The task is to determine the code for the word MOBILE. The provided example (MIRROR coded as NRILI) presents an unclear transformation pattern, potentially due to a typo or complexity not directly applicable to solving for MOBILE. Therefore, the solution focuses on identifying the pattern linking MOBILE to its code, NLYROV, based on the likely intended logic for this question type.

Identifying the Coding Pattern for MOBILE

Comparing MOBILE with its code NLYROV, we observe the following letter transformations:

  • M $\rightarrow$ N: The first letter M (13th in the alphabet) shifts to N (14th). The operation is $ +1 $.
  • O $\rightarrow$ L: The second letter O (15th) shifts to L (12th). The operation is $ -3 $.
  • B $\rightarrow$ Y: The third letter B (2nd) shifts to Y (25th). This involves wrapping around the alphabet: $ 2 - 3 = -1 $, which is equivalent to the 25th letter, Y ($ -1 \equiv 25 \pmod{26} $). The operation is $ -3 $.
  • I $\rightarrow$ R: The fourth letter I (9th) shifts to R (18th). The operation is $ +9 $.
  • L $\rightarrow$ O: The fifth letter L (12th) shifts to O (15th). The operation is $ +3 $.
  • E $\rightarrow$ V: The sixth letter E (5th) shifts to V (22nd). The operation is $ +17 $.

Resulting Code

The pattern identified is a sequence of specific shifts applied to each letter based on its position in the word: $ +1, -3, -3, +9, +3, +17 $. Applying this sequence to MOBILE correctly yields the code NLYROV.
