Percentage, hai kya? It’s like that extra helping of biryani – a small portion with a big impact. In real life, percentages rule the roost, from discounts on your favorite kurtas to calculating exam scores and gauging investment returns. But fear not, desi mitra! This guide unravels the percentage puzzle in simple, everyday Hindi, empowering you to conquer calculations with confidence.
Understanding the Basics:
What is a percentage? Soch lo, 100 rotiyon mein se 20 ko kha liya. That’s 20/100, which is 20%. Basically, percentage means “parts per hundred.” Just like we have 12 months in a year, a percentage tells you how much a part takes up out of a whole of 100.
Key Formula: Got it? Now, let’s crack the code with the magic formula:
Percentage = (Part / Whole) × 100
This is your secret weapon! Just plug in the values, and voila, the percentage pops out like a genie from a lamp.
Calculating Percentages: Real-World Examples:
Discounts: Wah! You spotted a 50% discount on that lehenga you love. But what’s the actual amount saved? Use the formula:
Discount (%) = (Marked Price – Selling Price) / Marked Price × 100
For example, a lehenga marked at ₹10,000 with a 50% discount would cost:
Discount = (10,000 – 5,000) / 10,000 × 100 = 50%
Hurray! You save ₹5,000, making the final price ₹5,000.
Exam Scores: Scored 75 marks out of 100 in Maths? Find your percentage with:
Percentage = (Marks Scored / Total Marks) × 100
So, your percentage is:
Percentage = (75 / 100) × 100 = 75%
Great job!
Beyond the Basics:
Percentage Change: Imagine your salary increases by ₹5,000 from ₹20,000. What’s the percentage increase?
Percentage Change = (Change / Original Value) × 100
Here, the change is ₹5,000 and the original value is ₹20,000.
Percentage Change = (5,000 / 20,000) × 100 = 25%
That’s a 25% raise – time to celebrate!
Tips and Tricks:
- Shortcut for dividing by 100: Remember, dividing by 100 is the same as moving the decimal two places to the left. So, 50% is essentially 50/100, which is 0.5.
- Mental Math Magic: For quick calculations, estimate the numbers. If you need to find 15% of 200, think: 10% of 200 is 20, so 15% would be slightly more, around 30.
Practice Makes Perfect:
Sharpen your skills with these real-life scenarios:
- Calculate the tip at a restaurant if the bill is ₹1,200 and you want to leave a 10% tip.
- Find out what percentage of your monthly income goes towards rent if your rent is ₹8,000 and your income is ₹30,000.
- Calculate the simple interest on a loan of ₹50,000 at 8% per annum for 2 years.
Remember: Practice makes perfect! The more you use percentages in daily life, the more comfortable you’ll become.
