Correct Answer: The original price of per meter cloth is Tk. 50 and current price is Tk. 40
Explanation:
At 20% reduction, When past price Tk. 100 then present price = (100 – 20) = Tk. 80
When past price Tk. 800 then present price = Tk. $\frac{80×800}{100}$= Tk. 640
The present price of 4 meters cloth = 800 — 640 = Tk. 160
The current price of 4 meters cloth = Tk. 160
The current price of 1 meters cloth = Tk. $\frac{160}{4}$
= Tk. 40
If present price Tk. 80 then past price = Tk. 100
If present price Tk. 40 then past price = Tk. $\frac{100×40}{80}$= Tk. 50
