a) Rs. 1005
b) Rs. 1000
c) Rs. 10125
d) None of the above
Answer: d
Explanation:
$$\eqalign{
& {\text{Principal}} \cr
& {\text{ = Rs}}{\text{.}}\left( {\frac{{100 \times 1000}}{{5 \times 4}}} \right) \cr
& = {\text{Rs}}{\text{. 5}}000 \cr
& {\text{Now, P = Rs}}{\text{.}}\,10000, \cr
& {\text{T = 2 years,}} \cr
& {\text{R = 5% }} \cr
& {\text{Amount}} \cr
& {\text{ = Rs}}{\text{.}}\left[ {10000 \times {{\left( {1 + \frac{5}{{100}}} \right)}^2}} \right] \cr
& = {\text{Rs}}{\text{.}}\left( {10000 \times \frac{{21}}{{20}} \times \frac{{21}}{{20}}} \right) \cr
& = {\text{Rs}}. 11025 \cr
& \therefore {\text{C}}{\text{.I}}{\text{. = }}\left( {11025 – 10000} \right) \cr
& \,\,\,\,\,\,\,\,\,\,\,\,\,\, = {\text{Rs}}. 1025 \cr} $$
