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

  • Work out GST, TDS, or commission percentages quickly
  • Useful for students, shoppers, accountants, and business owners alike
