In a store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains the same, what percent of profit could be made on the selling price?

সঠিক উত্তর: Option B
Let C.P.= Tk.100.
Then, Profit = Tk.320,
S.P. = Tk.420.
New C.P. = 125% of Tk.100 = Tk.125
New S.P. = Tk.420.
Profit = Tk.(420 - 125) = Tk.295
Required percentage = (295/420) * 100
= 70%(approx)
