Percentage Increase: New = Old × (1 + r/100). Percentage Decrease: New = Old × (1 - r/100).
Reverse Percentage — find original: If price increased by 20% to ₹600, original = 600 / 1.20 = ₹500.
Population/Price growth for multiple periods: Final = Initial × (1 + r₁/100) × (1 + r₂/100)...
If A is x% more than B → B is x/(100+x) × 100 % less than A.
Two successive changes of +x% and -x% always give a net loss of x²/100 %.
