Circular Seating Arrangement
Circular Seating Arrangement
Circular seating places people around a round table, and the one idea that decides every such set is the facing direction, because it silently reverses left and right. Candidates who memorise which way the table reads clear these sets quickly; those who guess lose the whole set to one flipped clue. In SBI Clerk a circular set of four to five questions is common, and the maths is trivial once you fix a single reliable convention for reading the circle.
Facing Centre versus Facing Outside
Everything hinges on where people look. When all face the centre, a person's left is the clockwise direction and their right is anticlockwise, from the reader's overhead view. When all face outside, it flips completely: their left becomes anticlockwise and their right becomes clockwise. This single reversal is the most tested trap in circular seating, so decide the facing direction before you interpret one left-or-right clue, and mark it on your diagram so you never forget mid-solve.
The Clockwise Reading Rule
Fix one convention and never change it: read the circle clockwise from a top anchor. Place the first fixed person at the top of the circle, then add neighbours by translating each clue into clockwise or anticlockwise steps using the facing rule above. A common SBI Clerk twist mixes directions, with some facing in and some facing out, so for those you must apply the left-right rule person by person rather than for the whole table at once.
| Clue | All face CENTRE | All face OUTSIDE |
|---|---|---|
| 'B to the right of A' | B is anticlockwise of A | B is clockwise of A |
| 'B to the left of A' | B is clockwise of A | B is anticlockwise of A |
| Reader's clockwise = person's | Left | Right |
Solved Example
Example: Six people sit around a table facing the centre. A is at top; B is to the immediate right of A. Facing centre means right = anticlockwise, so B sits one seat anticlockwise from A. If instead they faced outside, the same clue would place B one seat clockwise from A — same words, opposite seat.
✗ Reading 'right of A' as clockwise when everyone faces the centre | ✓ Facing centre: right = anticlockwise, so 'right of A' is one seat anticlockwise
Mixed Facing and Common Pitfalls
The hardest circular sets seat some people facing in and others facing out, and here you cannot apply one blanket rule. Handle each 'left/right' clue using the facing of the specific person named in that clue, not the person being placed. A neat check is that two neighbours facing opposite ways will read each other's left and right in opposite senses, which often resolves a stuck diagram. Also watch the difference between 'immediately next to' and merely 'to the left of', and remember that in a circle the two people at the 'ends' of any arc are still neighbours through the far side. Building the ring clockwise from one anchor and annotating each person's facing keeps even a mixed-direction set under control within a few minutes.
केंद्र की ओर मुख: व्यक्ति का दायाँ = घड़ी-विपरीत (anticlockwise)। बाहर की ओर मुख: दायाँ = घड़ी की दिशा। मिश्रित मुख में हर संकेत उसी व्यक्ति के मुख से पढ़ें जिसका नाम है।
Exam Pointer — Circular seating appears in most SBI Clerk Prelims papers as one 4-5 question set. The examiner's favourite trap is the facing direction flipping left and right, and mixed 'some in, some out' sets. Note the facing first, read the circle clockwise from one anchor, and budget about three to four minutes for the full set.
60-Second Recap
- Facing centre: right = anticlockwise, left = clockwise.
- Facing outside: everything reverses.
- Read the circle clockwise from one fixed anchor.
- Mixed facing: use the facing of the person named in each clue.
