To find the percentage change in price, we use the successive percentage change formula: Final Price = Initial Price ×(1− Decrease 1)×(1− Decrease 2)×(1− Decrease 3)×(1+ Increase ) Let the initial price be 100 units. After 55\% decrease: ⇒100×(1−0.55)=100×0.45=45 After 10\% decrease: ⇒45×(1−0.10)=45×0.90=40.5 After 20\% decrease: ⇒40.5×(1−0.20)=40.5×0.80=32.4 After 65\% increase: ⇒32.4×(1+0.65)=32.4×1.65=53.46 Percentage change in price from the original: ⇒ Percentage change =((53.46−100)∕100)×100 ⇒ Percentage change =(−46.54%) i.e. Decreases by 46.54%
