In a certain coding language 'KANPUR' is coded as 'JBMQTS'. How 'BOMBAY' will be coded in that language?

The correct option is APLCZZ.

To find how the word "BOMBAY" is coded, let us first analyze the relationship between the letters in the word "KANPUR" and its corresponding code "JBMQTS".

By comparing the positions of each letter in the English alphabet, we observe a pattern of alternating subtraction and addition by 1:

First letter: K becomes J
$K-1=J$
Second letter: A becomes B
$A+1=B$
Third letter: N becomes M
$N-1=M$
Fourth letter: P becomes Q
$P+1=Q$
Fifth letter: U becomes T
$U-1=T$
Sixth letter: R becomes S
$R+1=S$

The pattern is a sequential alternation of subtracting 1 (-1) and adding 1 (+1) to the alphabetical index of each character.

Applying this identical pattern to "BOMBAY":

1. First letter: B (-1) ⇒ A
2. Second letter: O (+1) ⇒ P
3. Third letter: M (-1) ⇒ L
4. Fourth letter: B (+1) ⇒ C
5. Fifth letter: A (-1) ⇒ Z (wrapping backward in the alphabet)
6. Sixth letter: Y (+1) ⇒ Z

Putting it all together, the letters form the coded word APLCZZ.
