There are three prices p for an item:
Price alteration details are in each case based on the latest price:
p0 = Original price
p1 = p0 * (1 + 0.5) ### after increase by 50%.
p2 = p1 * (1 - 0.3) ### after reduction by 30%.
Reconstruction of the original price p0, therefore, has in each case to be based on the immediately previous price:
p2 = Rs.3360
p1 = p2 / (1 - 0.3) -> 3360 / 0.7 = 4800
p0 = p1 / (1 + 0.5) -> 4800 / 1.5 = 3200
The original price for the machine was Rs.3200.
