The Formula
Sequential discounts
Final = Price × (1 − d₁/100) × (1 − d₂/100) × (1 − d₃/100)
Worked Example
Scenario: MRP ৳5,000 with 20% then extra 10%.
Step 1: After 20%: 5000 × 0.80 = 4000
Step 2: After extra 10%: 4000 × 0.90 = 3600
Step 3: True off = 28% (not 30%)

FAQ
Is 20% + 10% equal to 30% off?
No. After 20% off, a further 10% applies to the reduced price, so effective discount is 28% (0.8 × 0.9 = 0.72).
Does discount order matter?
For pure percentage discounts, the final price is the same regardless of order, but intermediate prices differ.
