Sabhi me ganit ek hi hai — (hissa ÷ poora) × 100. Marksheet ho, target ho ya kisi kaam ka hissa — formula nahi badalta, bas number badalte hain.
Ek chhoti si baat jo bahut kaam aati hai: agar poora number 500 hai to har 5 marks lagbhag 1% ke barabar hote hain. Isse aap bina calculator ke bhi mota-moti andaaza laga sakte hain — 387 me se 375 (yaani 75%) ke oopar 12 marks bache, jo kareeb 2.4% hue. Kul milakar lagbhag 77.4%.
Aur agar poora number 100 nahi hai to seedha ginna mushkil hota hai. Aise me pehle 10% nikaal lein (500 ka 10% = 50), phir usi se aage badhein. Ye tareeka dukan, mandi aur exam teeno jagah kaam karta hai.
Percentage ka matlab
"Percent" ka matlab hai har sau me. Yaani 15% ka matlab "har 100 me 15". Isliye kisi bhi rakam ka percent nikalne ka formula bahut aasaan hai.
Misaal: 500 ka 15% = (500 × 15) ÷ 100 = 75
Teen aam sawaal aur unka formula
- X ka Y% kitna? → (X × Y) ÷ 100
500 ka 15% = 75 - X, Y ka kitna percent hai? → (X ÷ Y) × 100
75, 500 ka 15% hai - X se Y tak kitne % badha/ghata? → ((Y − X) ÷ X) × 100
500 se 600 = 20% badha
Roz ke istemaal
Discount: ₹2,000 ki cheez par 30% chhoot = ₹600 kam, dena ₹1,400.
Marks: 450 me se 380 mile = (380 ÷ 450) × 100 = 84.4%.
Salary hike: ₹40,000 par 12% hike = ₹4,800 badha, nayi salary ₹44,800.
Tip: ₹850 ke bill par 10% = ₹85.
Ek galti jo sab karte hain
Agar koi cheez pehle 20% badhe aur phir 20% ghate, to wo wapas wahi nahi aati. Misaal: ₹100 par 20% badha to ₹120. Ab ₹120 par 20% ghata to ₹96 — ₹100 nahi. Wajah ye hai ki badhne ka percent ₹100 par laga tha aur ghatne ka ₹120 par. Share market aur discount ke mamlon me ye galti bahut mehngi padti hai.
Mun me percent nikalne ka trick
- 10% — decimal ek jagah baayein khiskao (₹850 → ₹85)
- 5% — 10% ka aadha
- 20% — 10% ka dugna
- 15% — 10% + uska aadha
Chaar asli misaal — rozana ke kaam se
1. Discount. ₹2,499 ki cheez par 40% off. Bachat = ₹999.60, dena hoga ₹1,499.40. Dukan me "40% + 10% extra" likha ho to wo 50% nahi hota — pehle 40% ghatega, phir bache hue par 10%. Asli discount lagbhag 46% banta hai.
2. Marks. 5 vishay, har ek 100 ka, kul 387 marks. Percentage = 387 ÷ 500 × 100 = 77.4%.
3. Salary hike. ₹35,000 se ₹42,000 hui. Badhotri = (42000 − 35000) ÷ 35000 × 100 = 20%.
4. GST nikalna. ₹5,900 me 18% GST shaamil hai. Base = 5900 × 100 ÷ 118 = ₹5,000, GST = ₹900. Seedha 18% ghatana galat jawab deta hai.
Log yahan galti kya karte hain
- Percentage jodna aur ghatana barabar maan lena. ₹100 par 10% badha to ₹110. Phir 10% ghata to ₹99 — ₹100 nahi. Ye sabse aam bhool hai.
- Do discount jod dena. "50% + 20% extra" 70% nahi hota. Pehle 50% (₹1,000 → ₹500), phir 20% (₹500 → ₹400). Asli discount 60% hua.
- Inclusive par seedha rate ghatana. Jab rakam me tax pehle se shaamil ho, to 100/(100+rate) wala formula lagta hai.
- Percentage point aur percent me farak na karna. Byaj 5% se 7% hua — ye "2 percentage point" ki badhotri hai, par asal me 40% ki badhotri hai.
- Ulta percentage. "20% badhne ke baad ₹6,000 hai, pehle kitna tha?" Jawab 6000 ÷ 1.2 = ₹5,000 hai, 6000 − 20% = ₹4,800 nahi.
Kaam ke shortcut
- 10% nikalna: decimal ek jagah baayein khiskao. ₹850 ka 10% = ₹85
- 5% nikalna: 10% ka aadha
- 15% (tip): 10% + uska aadha
- Ulta niyam: 8% of 50 = 50% of 8 = 4. Jo aasaan lage wo kar lein
- Rule of 72: 72 ÷ byaj dar = paisa dugna hone ke saal
Bharat me kahan zyada kaam aata hai
- GST: 5%, 12%, 18%, 28% — inclusive aur exclusive dono tarah ke hisaab
- Loan: byaj dar, processing fee (loan rakam ka %), prepayment charge
- Salary: hike %, PF katauti (basic ka 12%), HRA (basic ka 40/50%)
- Nivesh: return %, expense ratio, exit load
- Padhai: percentage, percentile aur CGPA — teeno alag cheezein hain

Percentage, percentile aur CGPA — teen alag cheezein
Ye teeno aksar mila diye jaate hain, jabki inka matlab bilkul alag hai:
- Percentage: aapne kul me se kitna paaya. 500 me se 400 = 80%.
- Percentile: aapse kitne pratishat log peeche hain. 90 percentile ka matlab 90% log aapse kam laaye — iska aapke marks se seedha koi rishta nahi.
- CGPA: grade point ka aausat. Ise percentage me badalne ka formula har board aur university ka apna hota hai — ek hi formula sab jagah nahi chalta.
Competitive exam me aksar percentile hi maayne rakhta hai, percentage nahi. Isliye "mere 85% aaye" aur "main 85 percentile par hoon" — ye do bilkul alag baatein hain.
Aksar pooche jaane wale sawaal
Percentage ka formula kya hai?
X ka Y% = (X × Y) ÷ 100. Misaal: 500 ka 15% = 75.
X, Y ka kitna percent hai — kaise nikaalein?
(X ÷ Y) × 100. Jaise 75, 500 ka 15% hai.
20% badhkar 20% ghatne se wahi rakam aati hai?
Nahi. ₹100 → 20% badha = ₹120 → 20% ghata = ₹96. Kyunki dono percent alag rakam par lage.
Discount ka hisaab kaise lagayein?
Daam ka discount percent nikaalein aur ghata dein. ₹2,000 par 30% = ₹600 kam, dena ₹1,400.
Marks ka percentage kaise nikaalein?
(Mile marks ÷ Kul marks) × 100. Jaise 450 me 380 = 84.4%.
