Correct Answer: ans.21%

Explanation:

The cost of 11 items are = Tk. 10

The cost of 1 items are = Tk.$\frac{10}{11}$ =

The selling price of 10 items are = Tk. 11

The selling price of 1 items are = Tk. $\frac{11}{10}$

The profit from 1 item = $\frac{\frac{11}{10}-\frac{10}{11}}{\frac{10}{11}}$ x100 Tk.= 21%
