RRB ALP CBT I 17 Feb 2026 Shift 2 Paper

Concept:Arrange six people on floors $1$ to $6$ using the given immediate-neighbour and distance conditions.Explanation:U lives on an odd floor above floor $1$, so U is on floor $3$ or $5$.B is immediately above U and A is immediately below U, so they occupy three consecutive floors.Only one person lives between U and P, so P is two floors away from U.K is immediately above D, and D is not on floor $1$.Testing U on floor $3$ gives B on $4$, A on $2$, and P on $1$; D and K then fit on $5$ and $6$.This satisfies all conditions.Thus, A lives on floor $2$.Answer:A
