If DELHI is written as GHOKL, how will MUMBAI be written?
PXPEBL
OTNABL
PWPEDL
PXPEDL
Correct answer: PXPEDL
Solution
From DELHI to GHOKL, each letter is shifted forward by 3 positions: D→G, E→H, L→O, H→K, I→L. Applying the same rule to MUMBAI gives M→P, U→X, M→P, B→E, A→D, I→L. So the code is PXPEDL.
