Circular Arrangement (Single Circle)

Introduction

Circular Arrangement (Single Circle) puzzle आपकी क्षमता को परखता है कि आप गोल मेज़ के चारों ओर लोगों या वस्तुओं की स्थिति को कैसे visualize और logically arrange करते हैं। यह एक foundational reasoning topic है, खासकर SBI PO, IBPS Clerk, SSC, CAT जैसे exams में।

मुख्य चुनौती directional clues को सही समझने में है - जैसे “left” और “right”, जो इस पर निर्भर करते हैं कि व्यक्ति center की ओर face कर रहा है या बाहर की ओर।

Pattern: Circular Arrangement (Single Circle)

Pattern

लोग एक गोल मेज़ के चारों ओर बैठे होते हैं, और उनकी स्थिति इस बात पर निर्भर करती है कि वे center की ओर face कर रहे हैं या बाहर की ओर।

  • Facing Center: Left = Anticlockwise, Right = Clockwise.
  • Facing Outward: Left = Clockwise, Right = Anticlockwise.
  • Immediate Neighbors: किसी व्यक्ति के बिल्कुल पास बैठे लोग।
  • Opposite Person: वह व्यक्ति जो ठीक सामने (180° apart) बैठा हो।

Step-by-Step Example

Question

छह लोग - A, B, C, D, E और F - एक गोल मेज़ के चारों ओर बैठे हैं और सभी center की ओर face कर रहे हैं। A, B के immediate left में है। D, A के opposite बैठा है। C, B और D के बीच बैठा है। E, A के पास नहीं बैठा है। F के immediate right में कौन बैठा है?

Options:
A) A    B) B    C) D    D) E

Solution

  1. Step 1: Fix first relation

    A, B के immediate left में है। सभी center की ओर face कर रहे हैं, इसलिए “left” = anticlockwise। यानी A, B के anticlockwise side पर बैठेगा।

  2. Step 2: Place D opposite A

    D को A के ठीक सामने रखें।

  3. Step 3: Use C’s clue

    C, B और D के बीच बैठता है → C को clockwise side पर रखें।

  4. Step 4: Use E’s restriction

    E, A के पास नहीं बैठ सकता → इसलिए E को D के पास opposite arc में बैठाएँ।

  5. Step 5: Fill the remaining seat

    आखिरी बची seat में F बैठेगा, जो E के पास होगा।

  6. Step 6: Find F’s right (facing center)

    Center-facing में “right” = clockwise। F के तुरंत clockwise बैठा व्यक्ति A है।

  7. Final Answer:

    A → Option A

  8. Quick Check:

    A left of B ✅ D opposite A ✅ C between B & D ✅ E not next to A ✅

Quick Variations

1. सभी center की ओर face कर रहे हों - आसान संस्करण।

2. Mixed facing directions (कुछ inward, कुछ outward)।

3. Single circle + extra attributes (color, city आदि)।

4. “Immediate left/right” या “second to the left/right” क्लू वेरिएंट्स।

Trick to Always Use

  • Step 1: हमेशा “opposite” या “immediate” pair clues से शुरुआत करें।
  • Step 2: facing direction का उपयोग करके left-right orientation तय करें।
  • Step 3: बाकी लोगों को elimination और adjacency logic से बैठाएँ।

Summary

Summary

  • Facing direction, left-right orientation को define करता है (center vs outward)।
  • “A opposite B” जैसे fixed pairs से शुरुआत करें ताकि circle lock हो जाए।
  • उसके बाद “immediate” और “between” relations रखें।
  • Final करने से पहले adjacency और non-adjacency नियम चेक करें।

याद रखने योग्य उदाहरण:
Center-facing में - Left = Anticlockwise, Right = Clockwise.

Practice

(1/5)
1. Six friends - A, B, C, D, E, and F - are sitting around a circular table facing the center. A sits second to the left of B. C sits opposite B. D is to the immediate right of E. Who sits to the immediate left of F?
easy
A. A
B. B
C. C
D. E

Solution

  1. Step 1: Place B and C (opposite)

    Fix B and C opposite each other.

  2. Step 2: Place A (second left of B)

    Facing center → left = anticlockwise. A is two seats anticlockwise from B.

  3. Step 3: Place D and E (D right of E)

    Facing center → right = clockwise. D is clockwise next to E.

  4. Step 4: Fill remaining seat for F

    The only remaining seat is between E and B (clockwise order example: B → F → E → D → A → C → B). Thus F’s immediate left (anticlockwise) is E.

  5. Final Answer:

    E → Option D
Hint: Fix opposites first, then place second-left/right, then immediate pairs, then leftover seat.
Common Mistakes: Placing second-left as clockwise instead of anticlockwise for center-facing.
2. Eight people - P, Q, R, S, T, U, V, and W - sit around a circular table facing the center. P is to the immediate left of Q. S sits opposite Q. V is to the right of S. Who sits second to the right of P?
easy
A. R
B. S
C. U
D. T

Solution

  1. Step 1: Place P and Q

    P immediate left of Q → anticlockwise from Q.

  2. Step 2: Place S opposite Q

    S directly across from Q.

  3. Step 3: Place V right of S

    Facing center → right = clockwise → V clockwise next to S.

  4. Step 4: Fill remaining seats

    Remaining people R, T, U, W. The only arrangement that fits all clues: clockwise from P: P → Q → R → S → V → T → U → W → P. Second right of P (clockwise) = R then U.

  5. Final Answer:

    U → Option C
Hint: When opposite and immediate clues are given, fix them first; remaining seats fill uniquely.
Common Mistakes: Placing right as anticlockwise for center-facing.
3. Seven people - A, B, C, D, E, F, and G - sit around a circular table facing the center. A sits third to the right of B. C is to the immediate left of A. F sits opposite D. Who sits second to the left of C?
medium
A. E
B. F
C. B
D. G

Solution

  1. Step 1: Place B and A

    A third right of B → clockwise three seats from B.

  2. Step 2: Place C left of A

    C immediate anticlockwise from A.

  3. Step 3: Place F opposite D

    F and D across from each other.

  4. Step 4: Fill remaining seats

    Remaining E, G. The arrangement (clockwise): B → G → E → A → C → F → D → B. Second left of C (anticlockwise) = A then B.

  5. Final Answer:

    B → Option C
Hint: When opposite and third-right clues are given, fix them first; the second-left falls out automatically.
Common Mistakes: Counting third-right as anticlockwise.
4. Six persons - L, M, N, O, P, and Q - sit around a circular table facing outward. L is to the immediate left of M. P sits opposite N. Who is to the immediate right of Q?
medium
A. M
B. N
C. L
D. O

Solution

  1. Step 1: Note facing direction

    All face outward → left/right directions are reversed (Left = Clockwise, Right = Anticlockwise).

  2. Step 2: L left of M (facing outward)

    Left = clockwise → L is clockwise to M.

  3. Step 3: P opposite N

    Place them directly across.

  4. Step 4: Find Q’s right

    Facing outward → right = anticlockwise. The person anticlockwise to Q is L.

  5. Final Answer:

    L → Option C

  6. Quick Check:

    Left-right reversal verified ✅
Hint: For outward-facing, reverse all left/right logic.
Common Mistakes: Applying inward logic (clockwise for right) to outward cases.
5. Eight people - A, B, C, D, E, F, G, and H - sit around a circular table facing the center. A sits opposite D. C sits to the immediate left of A. G sits opposite F. Who sits between H and B?
medium
A. E
B. F
C. C
D. G

Solution

  1. Step 1: Place A-D and G-F opposites

    Opposites fixed at 180° apart.

  2. Step 2: C left of A

    Facing center → left = anticlockwise → C sits immediately anticlockwise of A.

  3. Step 3: Complete circle with B, E, H

    Arrange remaining to balance gaps. E lies between H and B.

  4. Final Answer:

    E → Option A

  5. Quick Check:

    A↔D, G↔F, C left of A all verified ✅
Hint: Opposite pairs fix the circle; remaining neighbors can be fitted by adjacency clues.
Common Mistakes: Not visualizing positions when multiple pairs are opposite.
