IBPS Clerk Mains 29 Nov 2025 Paper

Concept:Apply a one-letter backward shift to the left part of the string, pick the required positions, and form meaningful four-letter words using one vowel at a time.Explanation:The given string is $\text{LBKFMQTVGINTPC}$.It contains 14 letters.The sixth element from the right end is $\text{G}$.So the letters to the left of $\text{G}$, i.e. positions 1 to 8, are shifted one letter backward.The changes are: $\text{L} \to \text{K}$, $\text{B} \to \text{A}$, $\text{K} \to \text{J}$, $\text{F} \to \text{E}$, $\text{M} \to \text{L}$, $\text{Q} \to \text{P}$, $\text{T} \to \text{S}$, $\text{V} \to \text{U}$.The remaining letters $\text{GINTPC}$ remain unchanged.So the new string becomes $\text{KAJELPSUGINTPC}$.Now take the 2nd, 4th, 5th, 7th, 8th, 10th and 12th letters: $\text{A, E, L, S, U, I, T}$.Using one vowel at a time and no repetition, the meaningful four-letter words formed are:With $\text{A}$: $\text{LAST}$With $\text{E}$: $\text{LEST}$With $\text{U}$: $\text{LUST}$With $\text{I}$: $\text{LIST}$The second letter of these words can be $\text{A, E, U}$ or $\text{I}$.Answer:All of these.
