Correct Answer: ans: Tk. 26.69%

Explanation:

The interest of Tk. 1200 for 3 years is Tk. = (2161 – 1200)Tk = Tk. 961

The interest of Tk. 1 for 3 years is Tk. = $\frac{961}{1200}$Tk.

The interest of Tk 1 for 1 years is Tk.=$\frac{961}{1200×3}$TK

The interest of TK 100 for 1 years is Tk. =$\frac{961×100}{1200×3}$=26.69%
