ans.The percentage of his profit is 20%
Explanation:
Total cost for per quintal rice = Tk. (985 + 10 + 5)

The selling price of per quintal rice = Tk. 1200
The total profit = (1200-1000)= Tk. 200
The 1000 makes profit = Tk. 200
The 100 makes profit =$\frac{200\times 100}{1000}$Tk.
= Tk. 20

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
= 21%
