Correct Answer: TK 80

Explanation:

At 12.5% loss, selling price = (100 — 12.5) Tk. = 87.5 Tk.

At 25% profit, selling price would be = (100 + 25) Tk. = 125 Tk.

Difference of selling price = (125 — 87.5) Tk. = 37.5 Tk.

Selling price Tk. 37.5 more when cost price = Tk. 100

Selling price Tk. 30 more when cost price =$\frac{100\cdot30}{37.5}$= 80 Tk.
