a) Rs. 12000
b) Rs. 12100
c) Rs. 12200
d) Rs. 12300
Answer: b
Explanation:
$$\eqalign{
& {\text{Rate }} \Rightarrow {\text{ 10% = }}\frac{1}{{10}} \cr
& {\text{Each installment of 2 years}} \cr
& \Rightarrow \frac{{10}}{{11}} \times \frac{{\left( {10 + 11} \right)}}{{11}} \times {\text{ Installment = P}}{\text{.A}} \cr
& {\text{P}}{\text{.A = 21000}} \cr
& {\text{Each installment = 12100}} \cr} $$
