Percentage kaise nikale?

Percentage nikalna bahut easy hai! Percentage ka matlab hota hai "prati sau" ya "har sau mein se kitna". Isse hum kisi bhi cheez ke hisse ko 100 ke scale par dikhate hain, jisse compare karna aur samajhna aasaan ho jaata hai.

Percentage nikalne ka basic formula yeh hai:

Percentage = (Part / Whole) × 100

Jahan:

• Part (Hissa): Woh quantity jiska percentage nikalna hai.
• Whole (Pura): Woh total quantity jiske reference mein percentage nikalna hai.

Chalo, kuch common situations mein percentage kaise nikalte hain, step-by-step dekhte hain:

1. Jab Aapko Marks ka Percentage Nikalna Ho (Ya kisi bhi Score ka)

Yeh sabse common tareeka hai jab aapko apne exam marks ya kisi bhi score ka percentage nikalna hota hai.

Steps:

1. Apne Prapt Ank (Obtained Marks) likho: Yeh woh marks hain jo aapko mile hain.
2. Kul Ank (Total Marks) likho: Yeh woh maximum marks hain jinke liye exam hua tha.
3. Formula mein daalo: Obtained Marks ko Total Marks se divide karo aur fir 100 se multiply karo.

Example: Maan lo aapko 500 mein se 400 marks mile hain.

• Obtained Marks = 400
• Total Marks = 500

Percentage = (400 / 500) × 100 Percentage = 0.8 × 100 Percentage = 80%

Toh, aapko 80% marks mile hain.

2. Jab Aapko Kisi Number ka Percentage Nikalna Ho (e.g., 20% of 150)

Agar aapko kisi di gayi quantity ka ek specific percentage nikalna hai, jaise "150 ka 20% kitna hoga?".

Steps:

1. Percentage ko Decimal mein badlo: Percentage ko 100 se divide karke decimal mein convert karo.
   • (e.g., 20% = 20 / 100 = 0.20).
2. Original Number se Multiply karo: Jo decimal value aayi hai, usse original number (jiska percentage nikalna hai) se multiply karo.

Example: 150 ka 20% kitna hoga?

• Percentage = 20%
• Original Number = 150

1. Percentage ko decimal mein badlo: 20 / 100 = 0.20
2. Multiply karo: 0.20 × 150 = 30

Toh, 150 ka 20% 30 hota hai.

3. Jab Aapko Original Number Nikalna Ho, Jab Percentage aur Uska Value Diya Ho (e.g., 30 is 15% of what number?)

Kabhi-kabhi aapko pata hota hai ki ek number ka ek specific percentage kitna hai, aur aapko woh original number dhundhna hota hai.

Steps:

1. Percentage ko Decimal mein badlo: Percentage ko 100 se divide karke decimal mein convert karo.
   • (e.g., 15% = 15 / 100 = 0.15).
2. Diye gaye Value ko Decimal se Divide karo: Jo value di gayi hai (jo percentage ka result hai), usse decimal percentage se divide karo.

Example: 30, kis number ka 15% hai?

• Value = 30
• Percentage = 15%

1. Percentage ko decimal mein badlo: 15 / 100 = 0.15
2. Divide karo: 30 / 0.15 = 200

Toh, 30, 200 ka 15% hai.

Important Tips:

• Practice: Jitni zyada practice karoge, utna hi percentage nikalna aapke liye aasaan ho jaayega.
• Calculator: Agar calculations bade hain ya aapko jaldi karna hai, toh calculator ka use kar sakte ho.
• Context: Hamesha dekho ki aap kis cheez ka percentage nikal rahe ho aur kis reference mein, taki aap sahi numbers use kar sako.
