Question

In a certain code language, if ABROAD is coded as 'RBAQCF', COUPLE is coded as 'UOCRNG', then what will 'DECADE' be coded as?

The correct answer is
CEDCFG

Coding Pattern Identification

Analyze the given examples:

  • ABROADRBAQCF
  • COUPLEUOCRNG

The coding rule involves:

  • Splitting the 6-letter word into two halves (first 3, last 3).
  • Reversing the first half.
  • Shifting each letter of the second half forward by 2 positions.

Verification with 'COUPLE':

  • First half 'COU' reversed is 'UOC'.
  • Second half 'PLE' shifted by +2 (P→R, L→N, E→G) becomes 'RNG'.
  • Combining yields 'UOCRNG', confirming the pattern.

Coding DECADE

Apply this pattern to the word DECADE:

  • First half: DEC
  • Second half: ADE

Processing the halves:

  • Reverse 'DEC' → CED
  • Shift 'ADE' by +2: A→C, D→F, E→G. Result → CFG

Combine the processed halves: CED + CFG = CEDCFG.

The coded word for 'DECADE' is CEDCFG.
