IBPS RRB PO Prelims 22 Nov 2025 Shift 2 Paper

Concept:This is a linear arrangement puzzle where seven travellers are placed on Monday to Sunday with one subject each.Formula:No formula is needed; use fixed-position clues and elimination of wrong cases.Solution:Exactly three persons travel after $Y$, so $Y$ is on Thursday.Two persons are between $Y$ and $J$, so $J$ can be Monday or Sunday.If $J$ is Monday, then $Z$ is Sunday, but then $M$ cannot have more than two persons between $M$ and $Z$.So $J$ is Sunday and $J$ studies Geography.After Sunday, count is $0$, so $Z$ is Monday.$L$ is immediately before $X$.$X$ studies English, and exactly one person is between $K$ and $X$.This gives Tuesday $L$, Wednesday $X$ – English, and Friday $K$.English is three days before Maths, so Maths is on Saturday.More than two persons are between $M$ and $Z$ (Monday), so $M$ is Saturday – Maths.Computer is immediately before History.Since $Z$ is not Computer, the Monday–Tuesday pair cannot be Computer–History.So Thursday–Friday is the pair: $Y$ – Computer and $K$ – History.Remaining subjects for $Z$ and $L$ are Reasoning and Science.$L$ does not study Reasoning, so $L$ – Science and $Z$ – Reasoning.Final arrangement:Thus the correct combination is $K$ – History.Answer:C. $K$ – History
