Example
You want to know the effective price after a 30% discount on ₹1,200: 30% of ₹1,200 = ₹360 discount → final price ₹840. Or reverse: if ₹840 is the price after a 30% discount, original price = ₹840 ÷ 0.70 = ₹1,200.
Why Use It
- Calculate discounts, markups, and profit margins instantly
- Find percentage change between two values (e.g. salary hike, price inflation)
- Work out GST, TDS, or commission percentages quickly
