Scene 1/13
Interactive — learn by doing. Drag, tap and explore to build the intuition.
Two discounts don't just add
20% then 10% off is NOT 30% off. Drag both and watch the real single discount.
Start
₹100
−20%→
After 1st
₹80
−10%→
After 2nd
₹72
net = -20 − 10 + (20×10)/100
-28% single discount
Just adding would say -30% — off by the 2 overlap. A flat 30% beats it for the buyer.
💡 Equal up-then-down by x% is never zero — it's always a fall of x²/100 %.
