Calculator Se Percentage Kaise Nikale? Formula aur Examples

Last updated on October 5th, 2026 at 06:10 pm

Calculator se percentage nikalna bahut aasan hai. Jo hissa (part) aapke paas hai, use total se divide kijiye aur 100 se multiply kar dijiye.

Percentage = (Part ÷ Total) × 100

Example: 600 me se 450 marks aaye. Calculator par dabaiye 450 ÷ 600 × 100 = aur answer aayega 75%.

Is guide me main aapko marks, discount, GST, percentage increase aur reverse percentage, sab kuch calculator par step by step dikhaunga. Yeh tarike normal calculator, mobile calculator aur scientific calculator, teeno par kaam karte hain.

Percentage kya hota hai?

Percentage ka matlab hai “har 100 me se kitna”. “Per cent” ka arth hi hai “prati sau”. Agar aapko 50% marks mile, to matlab har 100 me se 50.

Percentage ka sabse bada fayda yeh hai ki alag-alag total wali cheezon ki tulna aasan ho jaati hai. 600 me se 450 aur 500 me se 380 ko seedha compare karna mushkil hai. Lekin 75% aur 76% ko compare karna aasan hai.

Calculator me percentage nikalne ke 2 tarike

Tarika 1: Formula se (har calculator par chalta hai)

1. Part type kijiye, jaise 450.
2. ÷ dabaiye aur total type kijiye, jaise 600.
3. × dabaiye aur 100 type kijiye.
4. = dabaiye. Answer aayega 75.

Tarika 2: % button se

Zyadatar basic calculators par aap seedha 450 ÷ 600 % daba sakte hain aur screen par 75 aa jayega. Isi tarah 600 × 75 % dabane par 450 aayega, yaani 600 ka 75%.

Dhyan rakhiye: % button har calculator aur har mobile app me ek jaisa kaam nahi karta. Isliye pehle ek aisa sawal try kijiye jiska answer aapko pata ho, jaise 200 ka 10% = 20. Agar answer sahi aaye to button par bharosa kijiye. Warna Tarika 1 use kijiye, kyunki woh har calculator par sahi answer deta hai.

Marks ka percentage kaise nikale?

Marks % = (Mile hue marks ÷ Total marks) × 100

Example: 5 subjects hain aur har ek 100 marks ka hai. Aapke marks hain 78, 85, 69, 91 aur 72.

1. Saare marks jodiye: 78 + 85 + 69 + 91 + 72 = 395
2. Total marks nikaliye: 5 × 100 = 500
3. Calculator par dabaiye: 395 ÷ 500 × 100 = 79%

Kisi number ka percentage kaise nikale?

Sawal: 1,200 ka 18% kitna hota hai?

Number × Percentage ÷ 100

Calculator par dabaiye: 1200 × 18 ÷ 100 = 216

Shortcut: percentage ko decimal bana lijiye. 18% = 0.18, isliye 1200 × 0.18 = 216.

Discount percentage kaise nikale?

Sawal: Ek shirt ka MRP ₹2,499 hai aur us par 30% discount hai. Kitne paise dene honge?

1. Discount nikaliye: 2499 × 30 ÷ 100 = ₹749.70
2. Final price nikaliye: 2499 − 749.70 = ₹1,749.30

Ek hi step me: 2499 × 0.70 = ₹1,749.30. Kyunki 30% discount ka matlab hai ki aap 70% de rahe hain.

Ulta sawal: MRP ₹2,000 tha aur aapne ₹1,600 diye. Discount kitna percent mila? (2000 − 1600) ÷ 2000 × 100 = 20%.

Percentage increase aur decrease kaise nikale?

Change % = (Nayi value − Purani value) ÷ Purani value × 100

Example: Salary ₹25,000 se badhkar ₹28,500 ho gayi. Calculator par: (28500 − 25000) ÷ 25000 × 100 = 14% increase.

Agar answer minus me aaye, to woh decrease hai. Jaise ek share ₹500 se ₹425 par aa gaya: (425 − 500) ÷ 500 × 100 = −15, yaani 15% ki giravat.

Finance me yahi formula return nikalne ke kaam aata hai. Kai saal ka return nikalna ho to CAGR use hota hai, aur alag-alag tareekh par kiye gaye investment ke liye XIRR.

GST ya tax jodna aur hatana

GST jodna: ₹5,000 par 18% GST lagana hai. Calculator par: 5000 × 1.18 = ₹5,900.

GST hatana: Bill ₹5,900 ka hai jisme 18% GST shamil hai. Base price = 5900 ÷ 1.18 = ₹5,000.

Yahan sabse common galti hoti hai: log 5,900 ka 18% ghata dete hain. Usse ₹4,838 aata hai, jo galat hai. GST base price par laga tha, bill par nahi.

Percentage se original number kaise nikale?

Ise reverse percentage kehte hain. Sawal: 500 kisi number ka 40% hai. Woh number kya hai?

Original number = Value ÷ Percentage × 100

Calculator par dabaiye: 500 ÷ 40 × 100 = 1,250

Check kijiye: 1250 × 40 ÷ 100 = 500. Answer sahi hai.

Mobile calculator se percentage kaise nikale?

• Android aur iPhone: Calculator app kholiye aur formula type kijiye: 450 ÷ 600 × 100 =. Yeh tarika har phone par kaam karta hai.
• % button: Kai phones me % button seedha dikhta hai. Kuch phones me woh extra panel kholne par ya phone ko tedha karne par milta hai.
• Scientific calculator: % aksar SHIFT ke saath kisi key par hota hai. Exam me sabse safe tarika hai ÷ 100 use karna.

Excel me percentage kaise nikale?

• Marks ka percentage: cell me =B2/C2 likhiye aur cell ko Percentage format kar dijiye.
• Kisi number ka 18%: =A2*18%
• Percentage increase: =(B2-A2)/A2

Excel me aise formule roz ke kaam aate hain. Agar aap Excel achhe se seekhna chahte hain, to hamara Advanced Excel course dekhiye.

Percentage nikalte waqt 4 common galtiyan

1. Galat base lena. Increase ya decrease hamesha purani value par nikalta hai, nayi value par nahi.
2. Yeh maan lena ki 20% badhakar 20% ghatane se wahi number wapas aayega. Aisa nahi hota: 1,000 pehle 1,200 banta hai aur phir 960.
3. Percent aur percentage point ko ek samajhna. Interest rate 6% se 7% hua to yeh 1 percentage point ka izafa hai, lekin 16.67% ka increase hai.
4. × 100 bhool jana. 0.75 aur 75% ek hi baat hai. Calculator 0.75 dikhaye to use 100 se multiply kijiye.

Finance me percentage kahan use hota hai?

Finance ka lagbhag har number percentage me bola jaata hai: profit margin, growth rate, return aur interest rate. Kuch examples:

• Vertical analysis me balance sheet aur income statement ki har line ko percentage me likha jaata hai.
• Ratio analysis me margins aur returns percentage me nikalte hain.
• Annual return batata hai ki investment ek saal me kitne percent badha.
• Pro rata calculation me bhi hissa percentage se hi nikalta hai.
