In a certain code language, ‘ADULT’ is coded as ‘DAUTL’ and ‘TENSION’ is coded as ‘NETSNOI’. How will ‘OCEAN’ be coded in the same language?

  • A.COENA
  • B.CONAE
  • C.ECONA
  • D.COAEN

Answer: A

OCEAN is coded COENA. In ADULT the pair AD and the pair LT are reversed around the middle letter U, giving DAUTL. In TENSION the first three letters TEN and the last three ION are each reversed around the middle letter S, giving NET S NOI. So the rule is to reverse each block of letters on either side of the middle letter. OCEAN has five letters, so the blocks are OC and AN with E in the middle. Reversing gives CO, E, NA, which reads COENA. CONAE, ECONA and COAEN do not reverse both side blocks around the fixed centre.
