Q175
ReasoningCoding-Decoding
In a certain code, BREAKTHROUGH is written as EAOUHRBRGHKT. How is DISTRIBUTION written in that code?
  1. a.TISTBUONDIRI
  2. b.STTIBUONRIDI
  3. c.STTIBUDIONRI
  4. d.RISTTIBUDION

Answer: (C) STTIBUDIONRI

Splitting BREAKTHROUGH into consecutive letter-pairs (BR, EA, KT, HR, OU, GH, numbered 1-6) and comparing to the coded form EA-OU-HR-BR-GH-KT shows the pairs have been reordered as $2,5,4,1,6,3$. Applying this exact reordering to DISTRIBUTION's pairs (DI, ST, RI, BU, TI, ON) gives ST-TI-BU-DI-ON-RI, i.e. STTIBUDIONRI.
