Solution

Given:

Present value $$= ₹\ 11000$$
Interest rate $$= 10\%$$ per annum

Time $$=3$$ years

To find the amount we have the formula,

Amount $$(A) = P (1+(r/100))^n$$
where $$P$$ is the present value, $$r$$ is the rate of interest, $$n$$ is time in years.

Now substituting the values in above formula we get,

$$\therefore A = 11000 (1 +10/100)^3$$
$$\Rightarrow A = 11000 (11/10)^3$$
$$\Rightarrow A = 11000 (1331/1000)$$
$$\Rightarrow A = 11 (1331)$$
$$\Rightarrow A = ₹\ 14641$$

∴ Beeru has to pay $$₹\ 14641$$
