1Rs. 787.50
2Rs. 812.50
3Rs. 860
4Rs. 887.50

Answer:- 1

Explanation:-

Solution:

\begin{aligned} P = Rs . 16800 \\ R = 6 \frac{1}{4} % = \frac{25}{4} % \\ T = 9 mths = \frac{3}{4} yr . \\ ∴ S .I . = Rs . (16800 \times \frac{25}{4} \times \frac{3}{4} \times \frac{1}{100}) \\ = Rs . 787.50 \end{aligned}

$\eqalign{ & {\text{P}} = {\text{Rs}}{\text{. }}16800 \cr & {\text{R}} = 6\frac{1}{4}\% = \frac{{25}}{4}\% \cr & {\text{T}} = 9\,{\text{mths}} = \frac{3}{4}{\text{yr}}{\text{.}} \cr & \therefore {\text{S}}{\text{.I}}{\text{.}} = {\text{Rs}}{\text{.}}\left( {16800 \times \frac{{25}}{4} \times \frac{3}{4} \times \frac{1}{{100}}} \right) \cr & = {\text{Rs}}{\text{.}}\,787.50 \cr}$
