Correct Answer: D
Solution :
Sum = Instalment \[\left\{ \frac{20}{21}+{{\left( \frac{20}{21} \right)}^{2}}+{{\left( \frac{20}{21} \right)}^{3}} \right\}\] \[=2350\left( \frac{20}{21}+\frac{400}{441}+\frac{8000}{9261} \right)\] \[=2350\left( \frac{8820+8400+8000}{9261} \right)\] \[=2350\times \frac{25220}{9261}=Rs.6399.63\]You need to login to perform this action.
