A) Rs. 435
B) Rs. 450
C) Rs. 430
D) Rs. 432
Correct Answer: D
Solution :
\[CI=P\left[ {{\left( 1+\frac{R}{100} \right)}^{T}}-1 \right]\] \[246=P\left[ {{\left( 1+\frac{5}{100} \right)}^{2}}-1 \right]\] \[\Rightarrow \] \[246=P\left[ {{\left( \frac{21}{20} \right)}^{2}}-1 \right]\] \[\Rightarrow \] \[246=P\left( \frac{441-400}{400} \right)\] \[\Rightarrow \] \[246=\frac{41P}{400}\] \[\Rightarrow \] \[P=\frac{246\times 400}{40}\] \[=Rs.\,2400\] \[\therefore \] \[SI=\frac{\text{Principal}\times \text{Time}\times \text{Rate}}{100}=\frac{2400\times 3\times 6}{100}\] \[=Rs.\,432\]
