Coding-Decoding Pattern

MAT 2018 · Intelligence & Critical Reasoning · Medium · Coding Decoding

If CAUTIOUS is coded as BBTUHPTT, then NEGLIGENT is coded as ___.

  1. A.

    MFFMHFOS

  2. B.

    MFHMHHDMU

  3. C.

    MFFMHHDOS

  4. D.

    MFFMHJDOS

Answer

C

Explanation

Analyze the pattern between CAUTIOUS and BBTUHPTT:

  • C −1=-1 = B
  • A +1=+1 = B
  • U −1=-1 = T
  • T +1=+1 = U
  • I −1=-1 = H
  • O +1=+1 = P
  • U −1=-1 = T
  • S +1=+1 = T

The rule alternates between −1-1 and +1+1. Applying this to NEGLIGENT:

  • N −1=-1 = M
  • E +1=+1 = F
  • G −1=-1 = F
  • L +1=+1 = M
  • I −1=-1 = H
  • G +1=+1 = H
  • E −1=-1 = D
  • N +1=+1 = O
  • T −1=-1 = S

Result: MFFMHHDOS.
