Multiple choice general knowledge math & puzzles

If 'RAMANUJAN' is decoded as 'SBNBOVKBO' . Then 'CALCULATOR' is decoded as:

  1. DBDMBMSUP

  2. CLACULTAOR

  3. DBMDVMBUPS

  4. BZKBTKZSPQ
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The decoding pattern shifts each letter forward by 1 in the alphabet: R→S, A→B, M→N, etc. Applying this to 'CALCULATOR': C→D, A→B, L→M, C→D, U→V, L→M, A→B, T→U, O→P, R→S, giving 'DBMDVMBUPS'. Option A misses some shifts, B just rearranges letters, and D shifts by -1 instead of +1.

AI explanation

This is a Caesar cipher shifting every letter forward by 1 (R→S, A→B, M→N, and so on), which correctly transforms RAMANUJAN into SBNBOVKBO. Applying the same +1 shift to CALCULATOR (C→D, A→B, L→M, C→D, U→V, L→M, A→B, T→U, O→P, R→S) produces DBMDVMBUPS.
