Frequently asked questions
Is 20% + 10% the same as 30% off?
No. The second discount applies to the already reduced price: 100 → 80 → 72, an effective 28% off. The formula is 1 − (1 − a)(1 − b).
What is the real discount in “buy 2 get 1 free”?
You get 3 items for the price of 2, a 33.3% discount per item — only if you actually need all three.
Is GST charged on the discounted price?
Yes. When the discount is shown on the invoice at the time of sale, GST is calculated on the price after discount.
How do I calculate a discount percentage?
Discount % = (Original price − Sale price) ÷ Original price × 100. A ₹1,000 item selling for ₹750 has a 25% discount.
How do I calculate the price after discount?
Sale price = Price × (1 − Discount ÷ 100). For 30% off ₹2,000, the price is ₹1,400.
How do I find the discount between two numbers?
Subtract the sale price from the original price, divide by the original price and multiply by 100.
