✅ Pehle Yeh Aata Hai?
Yeh post shuru karne se pehle, in teen sawaalon ko 1 minute mein khud try kijiye:
- 3/5 ko percentage mein likho.
- 45% ko simplest fraction mein likho.
- 24 mein se 18 kitne percent hai?
Answers dekho
- 3/5 × 100 = 300/5 = 60%
- 45% = 45/100 = 9/20 (upar-neeche 5 se divide)
- 18/24 × 100 = 1800/24 = 75%
Teeno sahi? Badhiya, aage chaliye! Koi galat hua? Koi baat nahi, pehle Post 1: Percentage Kya Hai? ek baar padh lijiye, phir yahan wapas aaiye.

🎬 Kahani: Chintu Ka Ek Din
Subah 6 baje Chintu ki aankh khuli. Phone uthaya, screen pe likha tha: 🔋 15%. “Uff, charge karna bhool gaya!”
School pahuncha to notice board pe likha tha: “Exam dene ke liye 75% attendance zaroori hai.”
Lunch mein canteen wale bhaiya bole: “Aaj samose pe 10% off!”
Shaam ko TV pe news aayi: “Kal baarish ki sambhavna 80% hai.” Aur raat ko papa ke phone pe message aaya: “Aapka 90% data use ho chuka hai.”
Chintu ne socha, “Arre! Aaj to din bhar % hi % dikha!” Aapne dhyan diya? Ek hi din mein 5 alag jagah percentage aaya: battery, attendance, discount, mausam aur mobile data.
Aaj hum dekhenge ki percentage kahan-kahan chhupa hai, aur har jagah uska matlab kaise padhein. 😉

📖 Concept: Percentage Kahan-Kahan Use Hota Hai?
Step 1: Yaad karo, % ka ek hi kaam hai
Post 1 mein humne seekha: x% = x/100, yaani “har 100 mein se x”.
WHY yeh itna kaam ka hai? Kyunki duniya mein totals alag-alag hote hain (kisi class mein 40 bachche, kisi mein 55). Percentage sabko ek hi base, 100, pe le aata hai. Isliye jahan bhi “hissa” batana ho ya “tulna” karni ho, wahan percentage aa jaata hai.
Step 2: Percentage ke 5 bade kaam
| Kaam | Kahan dikhta hai | Example |
|---|---|---|
| 1. Hissa batana | Marks, attendance, battery, survey | “Class ke 35% bachche ladkiyan hain” |
| 2. Kisi cheez mein kya-kya mila hai | Kapde, khaane ke packet, hawa, sona | “60% cotton, 40% polyester” |
| 3. Tulna (compare) | Results, khel, voting | “School A ka result 92%, School B ka 88%” |
| 4. Paisa | Sale, bank, tax | “20% OFF”, “GST 18%” |
| 5. Sambhavna (chance) | Mausam ki bhavishyavani | “Baarish ki sambhavna 80%” |
WHY itni alag jagah ek hi cheez? Kyunki in sab mein ek hi sawaal chhupa hai: “Poore ka kitna hissa?” Aur is sawaal ka sabse aasaan jawab percentage deta hai.
Step 3: Koi bhi percentage wali line kaise padhein? (3 Sawaal)
Jab bhi aap “x%” padho, apne aap se yeh 3 sawaal poochho:
- Kiska percentage? Poora (total) kya hai? Jaise “75% attendance” mein total = school ke kul din.
- Kitna? Us total ke har 100 hisson mein se kitne? (75)
- Baaki kitna? 100% − x%. (100% − 75% = 25% din chhutti le sakte ho, usse zyada nahi)
WHY teesra sawaal kaam karta hai? Kyunki poori cheez = 100%. Agar uska ek hissa x% hai, to bacha hua hissa 100 − x hi hoga. Jaise 100 rupaye mein se 75 kharch hue to 25 bache.
Step 4: Saare hisse milke 100%
Agar kisi cheez ko alag-alag hisson mein baata jaaye (aur koi hissa do baar na gina jaaye), to saare percentages ka jod 100% hi hoga.
Jaise hawa: lagbhag 78% nitrogen + 21% oxygen + 1% baaki gases = 100%.
WHY? Kyunki saare hisse milke poori cheez banate hain, aur poori cheez = 100/100 = 100%. Yeh ek badhiya check bhi hai: agar aapke hisson ka jod 100% nahi aa raha, to kahin galti hai!
Step 5: Data ko percentage mein badalna
Newspaper, school aur sarkar apna data aksar percentage mein batate hain. Tareeka wahi Post 1 wala: (hissa ÷ total) × 100.
Jaise 50 bachchon ki class mein 20 bachche cycle se aate hain → 20/50 × 100 = 40%. Ab koi bhi, kisi bhi school se, is 40% ko apne school se compare kar sakta hai.

🔐 Deep Concept: Percentage ke 2 chhupe niyam
Niyam 1: Percentage bina total ke adhoora hai. “50% bachche aaye” sunke aap nahi bata sakte ki 5 aaye ya 500. Percentage sirf hissa batata hai, asli ginti nahi. Asli ginti ke liye total chahiye. (Total se asli number kaise nikalte hain, woh hum agle post, Post 3 mein padhenge.)
Niyam 2: “Jod 100%” sirf tab, jab hisse alag-alag hon. Agar survey mein har bachcha sirf ek favourite fruit chun sakta hai, to sabka jod 100% hoga. Par agar bachche ek se zyada fruit chun sakte hain, to ek hi bachcha do baar gina jaata hai, aur jod 100% se zyada bhi aa sakta hai! Isme koi galti nahi hai.
Asli samajh yeh hai: percentage padhte waqt hamesha dekho “poora kya hai” aur “koi cheez do baar to nahi gini gayi”.

✏️ Solved Examples
Example 1 (Easy): Hawa mein lagbhag 78% nitrogen aur 21% oxygen hai. Baaki gases kitne percent hain? Aur 100 litre hawa mein oxygen kitni hogi?
Baaki gases = 100% − 78% − 21% = 1%
21% = har 100 litre mein 21 litre, to 100 litre hawa mein oxygen = 21 litre (lagbhag).
WHY sahi hai? Poori hawa = 100%, isliye teeno hisse milke 100 hone chahiye: 78 + 21 + 1 = 100 ✅. Aur total hi 100 litre hai, to x% seedha x litre ban gaya.
📌 charumam.com
Example 2 (Medium): Ek school mein 150 bachchon ne Class 8 ka exam diya aur 135 pass hue. School ka pass percentage kitna hai? Fail percentage?
Pass % = 135/150 × 100 = 13500/150 = 90%
Fail % = 100% − 90% = 10%
WHY? 135/150 ko simplify karo: 15 se divide → 9/10 = 90/100 = 90%. Aur fail bachche = 150 − 135 = 15 → 15/150 × 100 = 10%. Dono tareekon se same jawab ✅. Isi tarah har saal schools apna “result %” batate hain.
📌 charumam.com
Example 3 (NCERT style): 40 bachchon se unka favourite khel poocha gaya (har bachche ne sirf ek khel chuna). Cricket 18, Football 10, Badminton 8, Kabaddi 4. Har khel ka percentage nikalo.
| Khel | Bachche | Percentage |
|---|---|---|
| Cricket | 18 | 18/40 × 100 = 45% |
| Football | 10 | 10/40 × 100 = 25% |
| Badminton | 8 | 8/40 × 100 = 20% |
| Kabaddi | 4 | 4/40 × 100 = 10% |
| Kul | 40 | 100% |
WHY check karein? 45 + 25 + 20 + 10 = 100. Har bachche ne sirf ek khel chuna, to saare hisse milke poori class (100%) banenge ✅. Shortcut: 40 bachche hain, to 1 bachcha = 100/40 = 2.5%. Cricket = 18 × 2.5 = 45%.

🧭 Kab Use Karein, Kab Nahi
| ✅ Percentage use karo jab… | ❌ Sirf percentage se kaam nahi chalega jab… |
|---|---|
| Poore ka hissa batana ho (class ka 45% cricket fans) | Asli ginti chahiye aur total pata hi nahi (“50% aaye” = 5 ya 500?) |
| Alag-alag size ki cheezein compare karni ho (do schools ka result) | Group bahut chhota ho (2 mein se 1 = 50%, sunne mein bada, par sirf 1) |
| Kisi cheez mein kya-kya mila hai (hawa, kapda, sona) | Ek hi cheez kai baar gini gayi ho (multiple choice survey), tab jod 100% maan ke mat chalo |

❌→✅ Worked Mistake
Sawaal: Rohan ke school mein 40% bachche bus se aate hain. Sohan ke school mein 50% bachche bus se aate hain. Kis school mein zyada bachche bus se aate hain?
❌ Galat: “50% bada hai 40% se, to Sohan ke school mein zyada bachche.”
Galti kya hai? Dono percentages alag-alag totals ke hain. Percentage hissa batata hai, asli ginti nahi.
✅ Sahi: Maan lo Rohan ke school mein 1000 bachche hain aur Sohan ke school mein sirf 100. To Rohan ke school mein har 100 mein se 40, yaani 10 × 40 = 400 bachche bus se. Sohan ke school mein 100 mein se 50 = 50 bachche. Yahan Rohan ka school bahut aage hai!
Sahi jawab: Jab tak dono schools ke kul bachche na pata hon, keh nahi sakte. Haan, itna zaroor keh sakte hain ki Sohan ke school mein bus wale bachchon ka hissa bada hai.
Doosri common galti: “Battery 20% bachi hai, to 20% use hui.” Nahi! 20% bachi hai to use hui = 100% − 20% = 80%. Hamesha dhyan se padho: bacha kitna, gaya kitna.

❓ FAQs (Bachchon Ke Asli Sawaal)
1. Percentage har jagah kyun use hota hai, fraction kyun nahi?
Fractions ke denominators alag-alag hote hain (18/40, 135/150…), inhe ek nazar mein samajhna aur compare karna mushkil hai. Percentage sabko 100 ke base pe le aata hai, aur 100 hamare dimaag ke liye sabse aasaan number hai. Isliye dukaan, school, bank, news, sab percentage bolte hain.
2. Kya saare percentages milke hamesha 100% hote hain?
Sirf tab, jab poori cheez ko alag-alag, bina overlap wale hisson mein baata gaya ho (jaise hawa ki gases, ya “sirf ek khel chuno” wala survey). Agar ek bachcha do jawab de sakta hai, to wahi bachcha do baar gina jaata hai, aur jod 100% se zyada ho sakta hai.
3. “Baarish ki 70% sambhavna” ka matlab kya hai?
Matlab: aise hi mausam wale 100 dinon mein se lagbhag 70 dinon mein baarish hoti hai. Yeh pakka nahi hai, par chance zyada hai, to chhata le jaana samajhdaari hai! ☔
4. Dukaan pe “Upto 50% OFF” likha ho to har cheez aadhe daam pe milegi?
Nahi! “Upto” ka matlab hai zyada se zyada 50%. Kuch cheezon pe 50% off hoga, kuch pe 10% ya 20%, aur kuch pe bilkul nahi. Percentage padhte waqt uske aas-paas ke shabd bhi dhyan se padho.
5. Agar sirf percentage pata ho, total nahi, to kya kaam ka?
Hissa samajhne ke liye kaafi hai (“aadhe se zyada bachche aaye” = 50% se zyada). Par asli ginti (kitne bachche) ke liye total zaroori hai. Total se asli number nikalna hum Post 3 mein seekhenge.
6. Cricket ka strike rate bhi percentage hai kya?
Soch same hai: “har 100 balls pe kitne run” (runs ÷ balls × 100). Par yeh poore ka hissa nahi hai, isliye ise % nahi likhte, aur yeh 100 se zyada bhi aa jaata hai (jaise 150). Isse pata chalta hai ki “har 100 pe” wali soch percentage ke bahar bhi kaam aati hai.

🧠 HOTS (Sochne Wale Sawaal)
Q1. Ek survey mein bachchon se poocha gaya, “Aapko kaun-kaun se fruit pasand hain? (jitne chaaho chuno)”. Result: Aam 70%, Kela 45%, Seb 30%. Jod 145% aaya. Kya survey mein galti hai?
Solution dekho
Nahi, galti nahi hai.
WHY: Har bachcha ek se zyada fruit chun sakta tha. Jaise kisi bachche ne aam aur kela dono chune, to woh aam ke 70% mein bhi gina gaya aur kela ke 45% mein bhi. Ek hi bachcha do baar gina gaya, isliye jod 100% se zyada aaya. Jod 100% tabhi hota hai jab har bachcha sirf ek jawab de.
Q2. Chintu ka phone subah 100% charge tha. 4 ghante baad battery 20% reh gayi (har ghante barabar battery ghati). Har ghante kitne percent battery gayi? Isi raftaar se phone aur kitni der chalega?
Solution dekho
4 ghante mein gayi = 100% − 20% = 80%.
Har ghante = 80% ÷ 4 = 20%.
Bachi 20% battery, har ghante 20% jaati hai → 1 ghanta aur.
Q3. Ek shirt ke label pe likha hai: “100% cotton, 20% polyester”. Kya yeh label sahi ho sakta hai?
Solution dekho
Nahi.
WHY: Shirt ka kapda alag-alag hisson se bana hai (koi dhaaga ek saath cotton aur polyester dono nahi ho sakta). To saare hisson ka jod 100% hona chahiye. Agar cotton hi 100% hai, to polyester ke liye jagah hi nahi bachi. 100 + 20 = 120% ek kapde ke liye namumkin hai. Label galat chhapa hai!
Q4. Ek test mein 20 sawaal hain, sab barabar marks ke. Ek sawaal kitne percent ka hai? Agar Meena ne 17 sahi kiye, to uska percentage kitna?
Solution dekho
Poora test = 100%, 20 sawaal → 1 sawaal = 100% ÷ 20 = 5%.
17 sahi → 17 × 5% = 85%. Check: 17/20 × 100 = 85% ✅

Solution dekho
Board 8 × 8 hai. Andar ka hissa (kinara hata ke) 6 × 6 = 36 squares.
Kinare wale = 64 − 36 = 28.
28/64 × 100 = 2800/64 = 43.75%.
Trap: 4 × 8 = 32 mat karo, kyunki 4 kone (corners) do baar gin jaate hain: 32 − 4 = 28 ✅

Chintu ka phone roz subah 100% hota hai aur raat tak khaali ho jaata hai. Isliye use roz charge karna padta hai, ek din ka charge poore hafte nahi chalta.
Padhai bhi bilkul aisi hi hai. Ek din 5 ghante padh ke phir 5 din chhutti, yeh kaam nahi karta. Roz thodi-thodi mehnat, poore focus ke saath, bina phone ke. Aaj 1% behtar, kal 1% aur. Sabr rakhiye, yeh chhote-chhote percent milke ek din 100% bante hain. 🔋🌱

🟢 Master Recap
- Percentage har jagah hai: marks, battery, kapde, khaana, sona, mausam, chunav, dukaan, bank.
- Iske 5 bade kaam: hissa batana, mixture batana, tulna, paisa, sambhavna.
- Har % line pe 3 sawaal: Kiska? Kitna? Baaki kitna (100% − x%)?
- Alag-alag hisse (bina overlap) milke hamesha 100%. Yeh ek badhiya check hai.
- “Per 100” dikhe (30 g per 100 g) to seedha percentage (30%).
- Percentage hissa batata hai, asli ginti nahi. Asli ginti ke liye total chahiye.
