In a code, DELHI is written as CDKGH. Which rule has been applied?
- A. one place forward
- B. one place backward
- C. two places backward
- D. reversal of the word
Explanation
D becomes C, E becomes D, L becomes K, H becomes G and I becomes H, each one place backward. Checking the last letter as well as the first guards against a rule that only appears to fit. A reversal would produce IHLED instead.
