Question

In a certain code language COMPUTER is written as RFUVQNPC. How will MEDICINE be written in that code language?

1. A. MFEDJOFM
2. B. MFBDPDQF
3. C. EOJDJEFM (Correct answer)
4. D. EOJDEJEM

Correct Answer

Option C — EOJDJEFM

Detailed Solution & Explanation

The correct answer is EOJDJEFM.

Key Points

• This is a coding-decoding question.
• The rule to convert COMPUTER → RFUVQNPC is: first reverse the word, then shift each interior letter one step forward in the alphabet, keeping the first and last letters of the reversed word unchanged.
• Reversing COMPUTER gives R-E-T-U-P-M-O-C; keeping the first (R) and last (C) as they are and moving the middle letters +1 gives R-F-U-V-Q-N-P-C = RFUVQNPC.
• Applying the same rule to MEDICINE: reverse it to E-N-I-C-I-D-E-M, keep the first E and last M unchanged, and shift the middle letters forward by one (N→O, I→J, C→D, I→J, D→E, E→F) to get E-O-J-D-J-E-F-M = EOJDJEFM, which is option (C).

Additional Information

• The rule here is reverse the word, then shift each letter by +1; checking a rule against the whole given pair before applying it is what prevents errors.
• Write the alphabet with positions (A=1 … Z=26) at the start of the reasoning section — nearly every coding question becomes mechanical once you can read positions off directly.
• The families to recognise: letter-shift, reversal, positional value, and substitution by a fixed key.
