Answer:
At the end of tenth year total interest will be 1,200 Tk.
Explanation:
Amount of interest in 10 years = 600 Tk.
Amount of interest in 1 years = $\frac{600}{10}$= 60 Tk.
In simple interest, when the principal is trebled, the interest will also be trebled.
Amount of interest in the first 5 years = 5 x 60 = 300 Tk.
And the amount of interest in the next 5 years = 60 x 5 x 3 = 900 Tk.
At the end of tenth year total interest will be = 300 + 900 = 1,200 Tk.
Answer:
960 pages.
Explanation:
We know, 24 minutes = 60 x 24 = 1,440 Seconds
9 Seconds is needed to copy = 6 pages
1 Second is needed to copy = $\frac{6}{9}$ pages
1,440 Seconds is needed to copy = $\frac{6\times 1440}{9}$ = 960 pages
