A certain sum of money (In $Rs.$) gives $Rs. 500$ at $5 \%$ S.I. for 1 year. What is the $C.I.$ at the same rate at the end of $2$ years?
A
$1050$
B
$1015$
C
$1035$
D
$1025$
Solution
Principal $=\frac{S I \times 100}{\text { Rate } \times \text { Time }}=\frac{500 \times 100}{5 \times 1}=$ Rs. 10000
$\Rightarrow$ Now CI at $5 \%$ rate $=1000\left[\left(1+\frac{5}{100}\right)^{2}-1\right]=$ Rs. 1025
