Formula Explained
Calculator ke peeche teen main formulas kaam karte hai. Chaliye teeno ko detail mein samajhte hai.
X% of Y Formula
Yeh sabse common percentage formula hai. Kisi bhi number ka kuch percent nikalna ho toh use karte hai.
Result = (X / 100) x Y
Jahan X = Percentage jo nikalna hai, Y = Jiska percent nikalna hai. Example, 20 percent of 500 = (20 / 100) x 500 = 100. Discount calculation mein yahi use hota hai. Agar 2,000 rupees ka item 25 percent discount par hai, toh discount = (25 / 100) x 2000 = 500 rupees.
X is What % of Y Formula
Yeh formula use hota hai jab aapko pata karna hai ki ek value doosri value ka kitna percent hai.
Percentage = (X / Y) x 100
Jahan X = Part value, Y = Total value. Example, agar aapne 50 marks score kiye out of 200, toh percentage = (50 / 200) x 100 = 25 percent. Exam results, market share, aur progress tracking mein yahi formula use hota hai.
Percentage Change Formula
Yeh formula do values ke beech kitna percent change hua yeh nikalne ke liye hai.
% Change = ((New - Old) / Old) x 100
Jahan New = Naya value, Old = Purana value. Positive result matlab increase, negative result matlab decrease. Example, agar salary 25,000 se 30,000 ho gayi, toh % change = ((30000 - 25000) / 25000) x 100 = 20 percent increase.
Step-by-Step Guide

Practical Examples
Example 1: Shopping Discount Calculation
Ramesh ek shirt kharid raha hai jiska original price 1,500 rupees hai aur 30 percent discount chal raha hai. Discount kitna milega aur final price kya hoga? Mode 1 use karo. X = 30 percent, Y = 1,500. Result = (30 / 100) x 1500 = 450 rupees discount. Final price = 1500 - 450 = 1,050 rupees. Sale shopping mein yeh calculation bahut helpful hai.
Example 2: Exam Marks Percentage
Sunita ne apne board exam mein 6 subjects mein total 486 marks score kiye out of 600. Percentage kya hai? Mode 2 use karo. X = 486, Y = 600. Percentage = (486 / 600) x 100 = 81 percent. Distinction mil jayegi kyunki 75 percent se zyada hai. Students ke liye yeh calculator result day par bahut useful hota hai.
Example 3: Salary Hike Percentage
Amit ka salary 40,000 rupees se 48,000 rupees ho gayi. Kitna percent increase hua? Mode 3 use karo. Old = 40,000, New = 48,000. % change = ((48000 - 40000) / 40000) x 100 = 20 percent increase. Appraisal time par yeh calculation har employee karta hai ki actual mein kitna percent hike mila.
Example 4: Price Decrease Calculation
Priya ne dekha ki uski favorite mobile phone ka price 25,000 se 18,000 kar diya gaya. Kitna percent discount mila? Mode 3 use karo. Old = 25,000, New = 18,000. % change = ((18000 - 25000) / 25000) x 100 = -28 percent. Yani 28 percent decrease. Sale season mein yeh calculation batati hai ki real discount kitna mil raha hai.
Example 5: Business Profit Percentage
Vikas ki shop ka monthly revenue 2,00,000 rupees hai aur profit 35,000 rupees hai. Profit margin percentage kya hai? Mode 2 use karo. X = 35,000, Y = 2,00,000. Percentage = (35000 / 200000) x 100 = 17.5 percent. Yani har 100 rupees ke sale par 17.50 rupees profit hai. Business analysis ke liye yeh calculator best hai.
Example 6: Restaurant Tip Calculation
Deepa restaurant mein 1,200 rupees ka bill pay kar rahi hai aur 10 percent tip dena chahti hai. Tip kitna hoga? Mode 1 use karo. X = 10 percent, Y = 1,200. Result = (10 / 100) x 1200 = 120 rupees.
