Ch 7: Blood Relations | Reasoning

Dosto, is chapter mein rishton ki paheliyan hoti hain — "Ek tasveer ki taraf ishara karke aadmi ne kaha: 'Ye mere pita ke iklaute bete ka beta hai' — wo ladka uska kya laga?"

Sunne mein ghumavdaar lagta hai, par tarika bahut aasan hai: kagaz par parivaar ka chhota ped (family tree) banao. Har rishta ek line ban jata hai, aur answer saamne aa jata hai.

CET Group D mein isse 1–2 questions aate hain. Sabse zaroori baat — generation (peedhi) aur ladka/ladki ka dhyan rakhna. Chalo, pehle rishton ke naam pakke karte hain! 💪

1. ⭐ Family Tree banane ka tarika

⭐ 3 niyam — bas itna hi ① Har peedhi (generation) ek line mein — dada-dadi upar, mata-pita beech mein, bachche neeche.
② Ladka = + ya square, Ladki = − ya circle (apna nishan fix rakho).
③ Pati-patni ko = se jodo, maa-baap se bachche tak seedhi line kheencho.

Upar se neeche peedhi, aur har vyakti par ladka/ladki ka nishan — bas yahi ek diagram poore chapter mein kaam aata hai.

2. ⭐ Rishton ki Table (ratt lo — sawal isi par hote hain)

Rishta (English)	Hindi/Hinglish
Father's brother	Chacha / Tau (paternal uncle)
Father's sister	Bua (paternal aunt)
Mother's brother	Mama (maternal uncle)
Mother's sister	Mausi (maternal aunt)
Mother's brother's wife	Mami
Father's father / mother	Dada / Dadi (paternal grandparents)
Mother's father / mother	Nana / Nani (maternal grandparents)
Son's wife	Bahu (daughter-in-law)
Daughter's husband	Damad (son-in-law)
Husband's/wife's brother–sister	Devar/Jeth · Nanad · Saala · Saali (in-laws)
Uncle's / aunt's children	Cousin (chachera/mamera/phuphera bhai-behen)
Brother's son / daughter	Bhatija / Bhatiji (nephew/niece)

📌 Paternal vs Maternal — 2 second ka rule Pita ki taraf = dada, dadi, chacha, bua (paternal) · Maa ki taraf = nana, nani, mama, mausi (maternal).
English mein "maternal uncle" dikhe to samajh jao mama, "paternal aunt" = bua.

3. ⭐ "Iklauta/Iklauti" wale famous sawal

⭐ Ye 3 line ratt lo — inhi par aadhe sawal bante hain "Mere pita ka iklauta beta" = main khud (agar bolne wala aadmi hai)
"Mere dada ka iklauta beta" = mera pita
"Mere pita ki maa ka iklauta beta" = mera pita

✏️ Solved Example 1 Tasveer dekh kar aadmi bola: "Ye mere pita ke iklaute bete ka beta hai." Ladka uska kya laga?
Step 1: "Pita ka iklauta beta" = wo aadmi khud
Step 2: To ladka uska BETA ✓

✏️ Solved Example 2 Rahul ne ek mahila ki taraf ishara karke kaha: "Ye mere dada ke iklaute bete ki beti hai." Mahila Rahul ki kya lagi?
Step 1: Dada ka iklauta beta = Rahul ke pita
Step 2: Pita ki beti = BEHEN ✓

4. Coded Blood Relations (nishan wale)

⭐ Har nishan ka matlab likh lo, phir aakhir se peeche chalo Maan lo: P + Q = P, Q ka pita · P − Q = P, Q ki maa · P × Q = P, Q ka bhai
Solved Example: A − B × C ka matlab?
Step 1: A − B → A, B ki maa
Step 2: B × C → B, C ka bhai (yaani B aur C bhai-behen)
Step 3: Jab A, B ki maa hai aur B–C bhai-behen hain → A, C ki bhi MAA ✓

5. Thode mushkil sawal (2 peedhi ke)

✏️ Solved Example — "Ram ki maa, Shyam ki maa ki iklauti beti hai" Step 1: Shyam ki maa ki iklauti beti = Ram ki maa
Step 2: Matlab Shyam aur Ram ki maa — dono ek hi maa ke bachche = bhai-behen
Step 3: Shyam = Ram ki maa ka bhai = Ram ka MAMA (maternal uncle) ✓

✏️ Solved Example — shaadi wala A ka beta B, B ki shaadi C se hui. C ki behen D ki shaadi E se hui, jo B ka bhai hai. D, A ki kya lagi?
Step 1: B aur E dono A ke bete hain
Step 2: D ki shaadi E se hui hai → D, A ke bete ki patni
Step 3: Yaani D = A ki BAHU (daughter-in-law) ✓

✏️ Type 1 — Tasveer/ishara wale ("pointing to a photo") Sabse common. Vakya ko tukdon mein todo aur andar se bahar solve karo. "Mere pita ka iklauta beta" ko pehle simplify karo (= main khud), phir aage badho.

✏️ Type 2 — Seedhi rishton ki chain (A, B, C, D) "A, B ka bhai hai; C, A ki maa hai; D, C ka pita hai" — har vakya ko tree par likhte jao, phir sawal padho. Tree ban gaya to answer 5 second ka.

✏️ Type 3 — Coded (+, −, ×, ÷ wale) Pehle har nishan ka matlab kinare likh lo. Phir expression ko aakhri jodi se peeche ki taraf solve karo.

✏️ Type 4 — Shaadi/in-law wale Pati-patni ko = se jodo. "Bete ki patni = bahu", "beti ka pati = damad" — in do line se zyadatar in-law sawal ban jate hain.

✏️ Type 5 — Paternal ya maternal poochna "Uncle" kaafi nahi — batana padta hai chacha (paternal) ya mama (maternal). Dekho rishta pita ki taraf se aaya ya maa ki taraf se.

Trick 1: Tree banao — dimaag mein mat rakho
Peedhi upar-neeche, pati-patni saath
2 minute ki paheli 20 second ki ho jati hai. Ye is chapter ka sabse bada hathiyar hai.

Trick 2: "Iklauta" wale ko turant badlo
Pita ka iklauta beta = main khud
Aisa dikhte hi use asli naam se replace kar do — vakya aadha chhota ho jayega.

Trick 3: Vakya ko AAKHIR se pado
"…ka beta" se shuru karo
"Mere pita ke bhai ki patni ka beta" → pehle "ka beta" chhodo, andar wala hissa solve karo (pita ka bhai = chacha; uski patni = chachi), phir uska beta = cousin.

Trick 4: Maa ki taraf = M se M
Maa → Mama, Mausi, Nana-Nani
Pita ki taraf = chacha, bua, dada-dadi. Ye do line paternal-maternal ki har galti rok deti hain.

Trick 5: Gender ka nishan mat bhoolo
+ ladka · − ladki
"A, B ka bachcha hai" mein A ladka hai ya ladki — pata na ho to answer bachcha/child hi rahega. Aksar sahi option isi baat par ban-bigad jata hai.

❌ Galti 1: Rishte ki DISHA palat dena "A, B ka pita hai" aur "B, A ka pita hai" — bilkul ulta! Tree banate waqt teer (arrow) ya upar-neeche ka kram sahi rakho.

❌ Galti 2: Paternal-maternal mila dena Mother's brother = mama (maternal uncle), father's brother = chacha (paternal uncle). Option mein dono hote hain — yahi asli imtihaan hai.

❌ Galti 3: Gender maan lena Naam se ladka-ladki mat tay karo (jaise "Kiran", "Suman" dono ho sakte hain). Jab tak sawal na bataye, gender maan ke mat chalo.

❌ Galti 4: Bolne wale (speaker) ko bhool jana "Mere pita ka iklauta beta" mein agar bolne wali aurat hai to wo khud nahi ho sakti — tab wo uska bhai hoga. Speaker kaun hai, ye pehle dekho.

❌ Galti 5: Cousin ko bhai/behen likh dena Chacha/mama ke bachche cousin hote hain, sage bhai-behen nahi. Exam mein dono options rakhe jate hain.

Blood relations ka ek hi asli hathiyar hai — family tree banana (peedhi upar-neeche, pati-patni ko =, aur + / − se ladka-ladki). "Iklauta/iklauti" wale vakyon ko turant simplify karo: pita ka iklauta beta = main khud, dada ka iklauta beta = mera pita. Lamba vakya ho to aakhir se peeche solve karo. Rishton ki table ratt lo aur paternal (pita ki taraf: dada, chacha, bua) vs maternal (maa ki taraf: nana, mama, mausi) ka fark kabhi mat bhoolna — yahi sabse zyada poocha jata hai. Aur do savdhaniyan: rishte ki disha ulti mat karo, aur gender maan ke mat chalo. 🚀
