Correct Answer: Option D
The S I for 5 years given = Tk.891 – Tk.540 = Tk.351
Then the rate of interest = (S I × 100)/ P n
= 351 × 100/540 × 5
= 13%.
After increase of 2% the new rate of interest = 15%
S I at this rate for 4 years = 540 × 15 × 4/100 = Tk.324
Therefore, the amount = P + S I = Tk.540 + Tk.324
= Tk.864.
