a) Rs. 12000
b) Rs. 6000
c) Rs. 8000
d) Rs. 10000
Answer: d
Explanation:
Amount = 12,100; r = 10%, t = 2 yrs
$$\eqalign{
& {\text{Amount}} = P{\left[ {1 + \frac{r}{{100}}} \right]^t} \cr
& 12100 = P{\left[ {1 + \frac{{10}}{{100}}} \right]^2} \cr
& 12100 = P{\left[ {\frac{{11}}{{10}}} \right]^2} \cr
& 12100 = P \times \frac{{11}}{{10}} \times \frac{{11}}{{10}} \cr
& P = \frac{{12100 \times 10 \times 10}}{{11 \times 11}} \cr
& P = 10000 \cr} $$
