Correct answer is: Rs 2,025
Explanation:
\(Principal = \Large \frac{SI \times 100}{Time \times Rate}\)
\(=\Large \frac{1200 \times 100}{4 \times 8}\)
=Rs.3750
\(\text{New principal }= 3×3750 = Rs.11250\)
\(\text{Therefore, S.I}. = \Large \frac{Principal \times Time \times Rate}{100}\)
\(=\Large \frac{11250 \times 3 \times 6}{100}\)
\(=Rs.2025\)
