A. Tk.8000
B. Tk.8250
C. Tk.9000
D. Tk.9250

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

Capital, P= 6000 tk

Capital + 4 Year's Interest = 7200 tk

4 Year's Interest = 7200-6000 = 1200 tk

1 Year's Interest = 1200/4 = 300 tk

Interest rate = (300÷6000)×100 = 5%

New Interest Rate, r = 5×1.5 = 7.5%

Year, n = 5

So, the amount = P ( 1 + n.r )

= 6000 { 1 + 5× (7.5÷100)}

= 6000 × 1.375

= 8250 tk.
