Hard

In a code, DELHI is written as CDKGH. Which rule has been applied?

Correct answer: B. one place backward

  • 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.

About Coding and Decoding

Coding and decoding questions replace letters, numbers, words or symbols with another pattern and ask you to identify the rule or decode a new item. Methods include alphabet positions, shifts, reversals, substitution, rearrangement, numerical values and separate rules for different parts of a code.
