DELHI Coding Pattern Analysis

The question asks us to find the code for "MUMBAI" based on the example coding of "DELHI" as "CDKGH". We need to identify the pattern used in the example.

Identifying the Coding Pattern

Let's compare the original word "DELHI" with its code "CDKGH" letter by letter:

  • D is coded as C (D - 1 letter = C)
  • E is coded as D (E - 1 letter = D)
  • L is coded as K (L - 1 letter = K)
  • H is coded as G (H - 1 letter = G)
  • I is coded as H (I - 1 letter = H)

The pattern is a simple reverse alphabet shift: each letter in the original word is replaced by the letter immediately preceding it in the alphabet.

Applying the Pattern to MUMBAI

Now, we apply the same "-1 letter" pattern to the word "MUMBAI":

  • M - 1 letter = L
  • U - 1 letter = T
  • M - 1 letter = L
  • B - 1 letter = A
  • A - 1 letter = Z (The alphabet wraps around, so the letter before A is Z)
  • I - 1 letter = H

Combining these resulting letters gives us the code for "MUMBAI": LTLAZH.
