Logical Reasoning(IBPS RRB PO) Puzzle Test

Direction: Read the given instructions and answer the following questions:

Eight persons are living in the apartment which has four floors and two flats. The bottom-most floor is numbered one and the topmost floor is numbered four. Each floor consists of two flats, flat P and flat Q where Q is in the west of flat P. Note: i) If X lives above Y, they must live in different types of flats. ii) If X lives below Y, they must live in the same type of flats. iii) If two floors between X and Y, then they must be living in the same flats.

R and T are not living on the same floor. W is not living on floor number 2. X lives below R. U lives above V who lives below S. Two floors are there between X and U. S lives in Flat P and Floor 4. Y and W live on the same floor but W is not living in Flat Q.

Four of the following are alike in a certain way and so form a group. Which one doesn’t belong to the group?

Explanation:

Let’s break it down, statement by statement:

- Eight people, four floors, two flats per floor (P is east, Q is west).

- If someone lives above another, their flats are different (if one’s in P, the other's in Q).

- Living below? Same flats.

- Two floors between X and Y? Then X and Y are in the same flat.

- S lives at the top (Floor 4), in flat P.

- Y and W share a floor, but only W is in flat P (because W isn’t in Q).

- W can’t be on Floor 2.

- X is below R. U is above V, who is below S. X and U are two floors apart.

- R and T? Not flatmates (different floors).

Grouping test:

Four of the names must share some pattern, one breaks it. The odd one out is someone whose flat/floor combination or adjacency doesn’t fit with the others.

Here’s how they generally break down:

- S: Floor 4, Flat P

- R: Not specified yet where, but must not share floor with T

- W: Shares floor with Y, not Flat Q, not on Floor 2

- V: Below S

- T: Not with R

From the information, most of these people (S, W, V, T) have hints aligning them specifically to a flat or floor, based on who’s above/below/sideways. R is pretty floaty—his position is flexible due to constraints but not specifics.

So the answer is:

Option 2: R

That’s because R doesn’t share a common trait as clearly as the other names—they’re all nailed to a flat/floor or directly adjacent to someone else. R just isn’t, and stands out. This makes him the odd one.
