Dosto, ab log gol ghere (circle) mein baithte hain. Pichhle chapter jaisa hi kaam hai — bas ek nayi cheez: munh andar (centre) ki taraf hai ya bahar ki taraf?
Isi ek baat se left-right poora palat jata hai, aur yahin sabse zyada students fasste hain. Par ghabrao mat — is chapter mein bas do line ratni hain, baaki sab pichhle chapter jaisa hi hai.
CET Group D mein circular paheli se 1–3 questions ek saath aate hain. Chalo, pehle wo do line pakki karte hain! 💪
1. ⭐ Do line jo pura chapter chalati hain
⭐ Circle ka master rule
Munh ANDAR (centre ki taraf) → LEFT = clockwise (ghadi ki disha), RIGHT = anticlockwise
Munh BAHAR (centre se ulta) → LEFT = anticlockwise, RIGHT = clockwise
Yaani bahar mukh karte hi sab kuch ulta — bilkul Chapter 9 ke south-facing wale case jaisa.
Munh BAHAR (centre se ulta) → LEFT = anticlockwise, RIGHT = clockwise
Yaani bahar mukh karte hi sab kuch ulta — bilkul Chapter 9 ke south-facing wale case jaisa.
2. Saamne wala (opposite) kaun?
⭐ Opposite = kul logon ka aadha aage
n logon ke circle mein saamne wala = n/2 sthan door (dono taraf se barabar).
6 logon mein → 3 sthan door · 8 logon mein → 4 sthan · 10 mein → 5 sthan.
⚠️ Visham (odd) sankhya ho — jaise 5 ya 7 log — to kisi ke theek saamne koi nahi hota!
6 logon mein → 3 sthan door · 8 logon mein → 4 sthan · 10 mein → 5 sthan.
⚠️ Visham (odd) sankhya ho — jaise 5 ya 7 log — to kisi ke theek saamne koi nahi hota!
3. Solved Puzzle A — 6 dost, munh ANDAR ki taraf
📋 Sawal
A, B, C, D, E, F ek gol mez ke aas-paas centre ki taraf munh karke baithe hain.
(i) C, A ke immediate left hai. (ii) B, A ke theek saamne hai. (iii) D, A ke immediate right hai. (iv) F, A ke 2nd to the right hai.
(i) C, A ke immediate left hai. (ii) B, A ke theek saamne hai. (iii) D, A ke immediate right hai. (iv) F, A ke 2nd to the right hai.
✏️ Hal — step by step
Step 1: Andar mukh → left = clockwise, right = anticlockwise. A ko kahin bhi baitha do.
Step 2: C, A ke immediate left → A se ek kadam clockwise.
Step 3: D, A ke immediate right → A se ek kadam anticlockwise. F, A ke 2nd right → do kadam anticlockwise.
Step 4: B, A ke saamne → 6 log hain to 3 sthan door.
Step 5: E bacha → jo ek jagah khaali hai wahin.
Final (clockwise padho): A → C → E → B → F → D ✓
Step 2: C, A ke immediate left → A se ek kadam clockwise.
Step 3: D, A ke immediate right → A se ek kadam anticlockwise. F, A ke 2nd right → do kadam anticlockwise.
Step 4: B, A ke saamne → 6 log hain to 3 sthan door.
Step 5: E bacha → jo ek jagah khaali hai wahin.
Final (clockwise padho): A → C → E → B → F → D ✓
📌 Isi paheli ke sawal
A ke saamne? → B · A ke 2nd left? → E · D ke immediate left? → A · E ke immediate right? → C · C aur B ke beech (clockwise) kaun? → E
4. Solved Puzzle B — 5 log, munh BAHAR ki taraf
📋 Sawal
P, Q, R, S, T ek circle mein bahar ki taraf munh karke baithe hain.
(i) Q, P ke immediate left hai. (ii) S, P ke immediate right hai. (iii) R, P ke 2nd to the right hai.
(i) Q, P ke immediate left hai. (ii) S, P ke immediate right hai. (iii) R, P ke 2nd to the right hai.
✏️ Hal
Step 1: Bahar mukh → left = anticlockwise, right = clockwise (sab ulta!)
Step 2: Q, P ke left → ek kadam anticlockwise. S, P ke right → ek kadam clockwise. R → do kadam clockwise.
Step 3: T bacha → aakhri khaali jagah.
Final (clockwise padho): P → S → R → T → Q ✓
R se Q ke beech (clockwise) kaun? → T · S ke 2nd left? → Q · P ke immediate right? → S
Step 2: Q, P ke left → ek kadam anticlockwise. S, P ke right → ek kadam clockwise. R → do kadam clockwise.
Step 3: T bacha → aakhri khaali jagah.
Final (clockwise padho): P → S → R → T → Q ✓
R se Q ke beech (clockwise) kaun? → T · S ke 2nd left? → Q · P ke immediate right? → S
5. Beech ke log aur "kitne door" ki ginti
⭐ Circle mein ginti DONO taraf se ho sakti hai
"X aur Y ke beech kitne log?" — circle mein do jawab bante hain (clockwise aur anticlockwise). Sawal padho ki kis taraf se pucha hai; na likha ho to chhota rasta lo.
Example: 10 logon ke circle mein do log 4 sthan door hain → beech mein 3 log (ek taraf se) aur doosri taraf 5 log.
Example: 10 logon ke circle mein do log 4 sthan door hain → beech mein 3 log (ek taraf se) aur doosri taraf 5 log.
6. Mile-jule (mixed) aur square wale sawal
- Mixed facing: kuch andar, kuch bahar — har banda par uske munh ka teer banao, aur uske hisaab se hi uska left-right lo.
- Square/rectangle table: 4 log kono (corners) par aur 4 bhujaon (sides) ke beech — niyam wahi circle wala.
- Circle mein rotation se koi fark nahi padta — A ko kahin bhi baitha sakte ho, sirf aapas ka kram (order) matter karta hai.
✏️ Type 1 — "X ke saamne kaun?"
n/2 sthan aage/peeche gino. 6 log → 3 sthan, 8 log → 4 sthan. Odd sankhya mein "saamne" hota hi nahi.
✏️ Type 2 — "X ke immediate/2nd left-right kaun?"
Pehle munh ki disha dekho (andar/bahar), phir clockwise ya anticlockwise gino. Yahi 80% sawal hain.
✏️ Type 3 — "X aur Y ke beech kitne log?"
Circle mein dono taraf ki ginti alag hoti hai. Sawal mein disha di ho to wahi lo, warna dono option dekho.
✏️ Type 4 — Bahar mukh wali paheli
Sabse zyada galti yahin. Diagram par har banda ke bahar ki taraf teer bana do aur left-right ulta lo.
✏️ Type 5 — Mixed facing / square table
Har vyakti ka apna teer. Square mein 4 kone + 4 bhuja — par niyam wahi: munh andar to left clockwise.
Trick 1: Do line ratt lo, baaki sab wahi
Andar → left ghadi ke saath · Bahar → ulta
Poora chapter inhi do line par hai. Baaki tarika Chapter 9 wala hi — dabbe (yahan circle), pakka clue, verify.
Andar → left ghadi ke saath · Bahar → ulta
Poora chapter inhi do line par hai. Baaki tarika Chapter 9 wala hi — dabbe (yahan circle), pakka clue, verify.
Trick 2: Pehle bande ko kahin bhi baitha do
Circle mein rotation se fark nahi
A ko upar (12 baje ki jagah) baitha do — aur wahi se saare clue lagao. Jagah "galat" hone ka darr mat rakho.

Trick 3: Saamne wala = n/2
6 → 3 · 8 → 4 · 10 → 5
Aur odd sankhya (5, 7) mein kisi ke theek saamne koi nahi hota — aisa option aaye to turant kaat do.
6 → 3 · 8 → 4 · 10 → 5
Aur odd sankhya (5, 7) mein kisi ke theek saamne koi nahi hota — aisa option aaye to turant kaat do.
Trick 4: Ghadi ka number socho
12, 2, 4, 6, 8, 10 baje wali jagah
6 logon ke liye ghadi ke ye 6 nishan use karo — clockwise/anticlockwise ginna aasan ho jata hai.
12, 2, 4, 6, 8, 10 baje wali jagah
6 logon ke liye ghadi ke ye 6 nishan use karo — clockwise/anticlockwise ginna aasan ho jata hai.
Trick 5: Bahar mukh dikhte hi "ULTA" likh do
Diagram ke kone mein bada sa ULTA
Ye ek shabd poori paheli mein yaad dilata rahega ki left-right palta hua hai.

Ye ek shabd poori paheli mein yaad dilata rahega ki left-right palta hua hai.
❌ Galti 1: Bahar mukh mein bhi andar wala niyam lagana
Ye is chapter ki sabse badi galti hai. Bahar munh = left anticlockwise. Ek shabd "ULTA" diagram par likh dena kaafi hai.
❌ Galti 2: Apna left-right lagana
Jo banda upar (12 baje) baitha hai aur andar dekh raha hai, uska left aapko daayi taraf dikhega. Hamesha uske hisaab se socho.
❌ Galti 3: Odd sankhya mein "saamne" dhundna
5 ya 7 logon ke circle mein kisi ke theek saamne koi nahi hota. Aisa sawal ho to samjho koi aur baat pucha ja rahi hai.
❌ Galti 4: "Beech mein kitne" ka ek hi jawab maan lena
Circle mein dono taraf ki ginti alag hoti hai (jaise 3 aur 5). Sawal ki disha dhyan se padho.
❌ Galti 5: Mixed facing mein sabka ek hi niyam
Agar kuch log andar aur kuch bahar dekh rahe hain to har ek ka apna left-right hoga. Har bande par alag teer banao.

Poora chapter do line par hai: munh andar → left = clockwise, munh bahar → left = anticlockwise (sab ulta). Saamne wala n/2 sthan door hota hai (6 → 3, 8 → 4), aur odd sankhya (5, 7) mein kisi ke theek saamne koi nahi hota. Circle mein rotation se fark nahi padta — pehle bande ko kahin bhi baitha do, sirf aapas ka kram matter karta hai. "Beech mein kitne log" ka circle mein do jawab bante hain — disha dhyan se padho. Mixed facing ho to har bande par apna teer banao. Aur sabse badi galti se bacho: bahar-mukh wali paheli mein niyam palatna mat bhoolna — diagram par bada sa "ULTA" likh do! 🚀
