In a certain code, CLOUD is written as GTRKF. How is SIGHT written in that code?

  • A.UGHHT
  • B.UHJFW
  • C.WFJGV
  • D.WGJHV

Answer: D

Correct answer: WGJHV

Reverse the word, then apply an alternating shift of three forward and one back. CLOUD reversed is DUOLC, and D+3=G, U−1=T, O+3=R, L−1=K, C+3=F gives GTRKF. SIGHT reversed is THGIS, so T+3=W, H−1=G, G+3=J, I−1=H, S+3=V, giving WGJHV.
