1. Harun invested Tk,10000 in Grameen Mutual Fund account exactly 3 years ago. The value of the account increased by 10% during the first year, increased by 5% in the second year and decreased by 10% during the third year. What is the value of the account today?
- A. Tk.10350
- B. Tk.10350
- C. Tk.10350
- D. Tk.10350
Answer: Option B
Explanation:
a+b+(ab)/100
=10+5+(10×5)/100
=15.5%
Again,
a'+b'+(ab)'/100
=15.5-10-(15.5×10)/100
=3.95%
So, 10000+(10000×3.95%)=10395
