In a certain code language, ‘DRIVER’ is coded as ‘RDVIRE’ and ‘TRIANGLE’ is coded as ‘RTAIGNEL’. How will ‘BRIDGE’ be coded in the same language?

  • A.IRBEGD
  • B.RIEBDG
  • C.RBDIEG
  • D.IREBGD

Answer: C

BRIDGE is coded as RBDIEG (option C). In the examples the letters are taken in pairs and the two letters of each pair are swapped: DR becomes RD, IV becomes VI, ER becomes RE, which gives RDVIRE; and TR, IA, NG, LE become RT, AI, GN, EL, which gives RTAIGNEL.

BRIDGE splits into BR, ID, GE, and swapping inside each pair gives RB, DI, EG, so RBDIEG. The other options either swap the wrong letters or move whole blocks, which neither example does.
