If IMAGE and FIELD are coded as FHBNJ and EMFJG respectively then, which one among the given options is the most appropriate code for BEACH ?

  • A.CEADP
  • B.IDBFC
  • C.JGIBC
  • D.IBCEC

Answer: B

The code for BEACH is IDBFC.

Find the rule from IMAGE → FHBNJ. Write IMAGE backwards, E G A M I, and move each letter one place forward in the alphabet: F H B N J. FIELD backwards is D L E I F, and one step forward gives E M F J G, matching the given code.

Apply the same rule to BEACH: backwards it is H C A E B, and one step forward gives I D B F C.

CEADP, JGIBC and IBCEC do not follow the reverse-and-shift rule; IBCEC, for example, starts correctly with I but then fails at the second letter, which must be C + 1 = D.
