A
$Rs. 500(1.1)^{10}$
B
$Rs. 500(1.1)^{10}$
C
$Rs. 500(1.1)^{10}$
D
$Rs. 500(1.1)^{10}$
Solution
The amount deposited in the bank is $Rs.$ $500 .$
At the end of first year, amount $= Rs .500\left(1+\frac{1}{10}\right)= Rs .500(1.1)$
At the end of $2^{\text {nd }}$ year, amount $=$ $Rs.$ $500(1.1)(1.1)$
At the end of $3^{ rd }$ year, amount $= Rs.\, 500(1.1)(1.1)(1.1)$ and so on
$\therefore$ Amount at the end of $10$ years $=$ $Rs.$ $500(1.1)(1.1) \ldots . .(10 \text { times })$
$= Rs. 500(1.1)^{10}$
