Frequently asked questions
10% up then 10% down — back to start?
No! ₹100 → 110 (up 10%) → 99 (down 10% of 110). Asymmetry is a common trap in retail pricing and investing.
How do discounts stack?
30% + 10% extra isn't 40% off. It's 37% off (0.7 × 0.9 = 0.63, so 37% discount total).
Negative % increase = decrease?
Yes, mathematically equivalent. Some calculators accept negative increase.
Bps (basis points)?
1 basis point = 0.01%. Used in finance for small rate changes. 25 bps = 0.25% rate change.
