Kya aapko kabhi bazaar mein shopping karte waqt, ya dosto ke sath restaurant ka bill split karte waqt percentage calculate karne mein pareshani hui hai? Ya phir school/college ke exams ka result aane par aap confuse ho jate hain ki aakhir percent kaise nikalte hai? Agar haan, toh aap akele nahi hain. Desh bhar mein lakhon log har din internet par search karte hain ki percentage kaise nikala jata hai.
Percentage (प्रतिशत) nikalna koi mushkil kaam nahi hai. Yeh ek behad basic aur zaroori mathematical skill hai, jo hamare daily life ke lagbhag har hisse mein kaam aati hai—chahe aapko kisi product par milne wala discount calculate karna ho, bank loan ka interest nikalna ho, ya phir salary hike assess karni ho. Is detailed guide mein hum aapko sabse aasan bhasha mein percentage nikalne ke tarike aur shortcuts sikhayenge. Chaliye shuru karte hain!
1. Percentage Kya Hai? (Understanding the Concept)
Isse pehle ki hum formulas aur calculations par jayein, yeh samajhna zaroori hai ki aakhir percentage hota kya hai.
Percentage do shabdon se milkar bana hai: "Per" (yani har ek par) aur "Cent" (yani 100). Hindi mein isse "Pratishat" (प्रतिशत) kehte hain, jahan 'prati' ka matlab hai 'har ek' aur 'shat' ka matlab hai 'sau (100)'.
Asan shabdon mein kahein toh, kisi bhi sankhya (number) ko jab hum 100 ke scale par evaluate karte hain, toh use percentage kehte hain. Iska symbol % hota hai.
Udaharan ke liye:
- Agar kisi exam mein aapke 80% marks aaye hain, toh iska matlab hai ki aapne har 100 marks mein se average 80 marks score kiye hain.
- Agar kisi shop par 20% discount chal raha hai, toh iska matlab hai ki aapko har 100 rupaye ki kharidari par 20 rupaye ki chhoot milegi.
2. Percent Nikalne Ka Formula (The Core Mathematical Formula)
Percentage nikalne ka ek universal formula hota hai, jise aap duniya ke kisi bhi percentage calculation ke liye apply kar sakte hain. Chahye aap school ke student hon ya koi business owner, yeh percent nikalne ka formula aapke humesha kaam aayega:
Percentage (%) = (Obtained Value / Total Value) × 100
Hindi mein kahein toh: प्रतिशत (%) = (प्राप्त मान / कुल मान) × 100
Is Formula Ko Kaise Use Karein? (Step-by-Step Example)
Maan lijiye ki aapne ek exam diya jiska total marks (purnank) 600 tha. Exam ka result aane par aapko pata chala ki aapne 450 marks score kiye hain. Ab aapko nikalna hai ki aapka kitna percentage aaya.
- Step 1: Obtained Value (Prapt marks) ko identify karein = 450
- Step 2: Total Value (Total marks) ko identify karein = 600
- Step 3: Formula apply karein: Percentage = (450 / 600) × 100
- Step 4: Calculation karein: (450 / 600) = 0.75 0.75 × 100 = 75%
Toh iska matlab hua ki aapne exam mein 75% marks hasil kiye hain. Yeh formula sabhi jagah standard tarike se kaam karta hai.
3. Mobile Phone Calculator Se Percentage Kaise Nikalte Hai?
Aaj ke samay mein hum sabhi ke paas smartphone hota hai. Jab bhi hum bazaar mein hote hain ya jaldi mein hote hain, toh hum pen-paper lekar calculation nahi karte. Aise mein mobile phone calculator ka use sabse best aur fast option hai.
Agar aapko janana hai ki percentage kaise nikalte hai calculator par, toh iske do alag-alag tarike hain:
Method 1: Direct Percentage (%) Key Ka Use Karke

Method 2: Division (Bhag) Method (Agar % button na ho toh)
Agar aap kisi aisi device ya normal purane calculator ka use kar rahe hain jisme % ka button nahi hai, toh aap is generic method ka use kar sakte hain.
Example: Aapko 40,000 ka 12 percent nikalna hai.
- Calculator par type karein: 40000
- Multiplication (×) dabayein aur phir 12 type karein.
- Ab division (÷) yani bhag ka button dabayein.
- Phir 100 type karein aur Equals (=) dabayein.
- Aapka calculation hoga: (40000 × 12) / 100 = 4800
Yeh dono hi tarike percentage kaise nikalte hai calculator par ke sabse simple aur reliable mathematical paths hain.

Har baar calculator nikalna possible ya convenient nahi hota. Agar aapko bazaar mein koi product kharidte waqt instant dimag mein calculation karni hai, toh aap in super-fast mental math tricks ka use kar sakte hain.
Trick 1: The "10% Rule" (Sabse Behtareen Tarika)
Kisi bhi number ka 10% nikalna duniya ka sabse aasan kaam hai. Aapko bas us number ke aakhri digit se pehle ek decimal (dot) lagana hai, ya agar aakhri digit zero (0) hai toh use hata dena hai.
- 10% of 500 = 50 (Humne ek zero hata diya)
- 10% of 1250 = 125
- 10% of 85 = 8.5 (Humne ek digit ke pehle decimal laga diya)
Trick 2: The "1% Rule"
Jaise 10% nikalne ke liye hum ek digit chhodkar decimal lagate hain, waise hi 1% nikalne ke liye hum do digit chhodkar decimal lagate hain.
- 1% of 6000 = 60
- 1% of 450 = 4.5
- 1% of 99 = 0.99
In Tricks Ko Combine Kaise Karein?
Agar aapko yeh dono rules samajh aa gaye, toh aap koi bhi random percentage apne dimag mein hi calculate kar sakte hain. Chaliye dekhte hain kaise:
Example: Aapko 4000 ka 15% nikalna hai.
- 15% ko do parts mein divide karein: 10% + 5%.
- Sabse pehle 4000 ka 10% nikalein = 400 (using 10% rule).
- Ab agar 10% = 400 hai, toh 5% uska aadha hoga yani 200.
- Dono ko add kar dein: 400 + 200 = 600.
- Dekha aapne? Bina kisi pen ya calculator ke aapne 15% nikal liya!
Example: Aapko 8000 ka 12% nikalna hai.
- 12% ko divide karein: 10% + 1% + 1%.
- 8000 ka 10% = 800.
- 8000 ka 1% = 80.
- Toh 12% = 800 + 80 + 80 = 960.
6. School Aur College Ke Marks Ka Percentage Kaise Nikale?
Students ke beech mein yeh sawal sabse zyada pucha jata hai ki "percentage kaise nikalta hai hamare board exams ka?". Chaliye isko ek dam clear tarike se samajhte hain.
Case 1: Jab sabhi subjects ke maximum marks 100 hon
Agar aapke paas 5 subjects hain aur har subject 100 marks ka hai, toh total marks hue 500. Maan lijiye aapke score is tarah hain:
- Physics: 75
- Chemistry: 80
- Maths: 95
- English: 85
- Hindi: 90
- Total Obtained Marks = 75 + 80 + 95 + 85 + 90 = 425
- Total Maximum Marks = 500
- Formula Apply Karein: (425 / 500) × 100
- Calculation: 425 / 5 = 85%
Short Cut Trick: Agar har subject 100 marks ka hai, toh aapko bas apne saare obtained marks ko plus karna hai aur total number of subjects (is case mein 5) se divide kar dena hai. Aapka percentage turant nikal aayega.
Case 2: CGPA Se Percentage Kaise Nikalein (CBSE Board)
CBSE aur kayi boards mein marks ke bajaye CGPA (Cumulative Grade Point Average) diya jata hai. Isse percentage mein badalne ka ek standard formula CBSE dwara taya kiya gaya hai:
Percentage = CGPA × 9.5
- Agar aapka CGPA 8.5 aaya hai:
- Calculation: 8.5 × 9.5 = 80.75%
- Agar aapka CGPA 9.2 aaya hai:
- Calculation: 9.2 × 9.5 = 87.4%
7. Shopping Discount Kaise Calculate Karte Hai?
Jab aap kisi mall ya online store par shopping karte hain, toh aapko aksar discount offers milte hain jaise "Buy Jeans at Rs. 3000 with 40% Off". Aise mein product ki final effective price nikalne ka aasan tarika yeh hai:
- Original Price: Rs. 3000
- Discount Rate: 40%
- Sabse pehle discount value nikalein: (3000 × 40) / 100 = 1200
- Ab original price mein se discount value ko minus kar dein: 3000 - 1200 = 1800
- Yani aapko jeans Rs. 1800 mein milegi.
Shortcut Method: Agar kisi product par 40% discount hai, toh iska matlab hai ki aapko uski cost ka sirf 60% (100% - 40%) pay karna hai. Aap direct original amount ka 60% nikal sakte hain:
- 3000 ka 60% = (3000 × 60) / 100 = 1800.
- Is single-step calculation se aapka kaafi time bachega.
