Total investment in Khammam in $1995 = 7081.6$

Total investment in Khammam in $1996 = 8352$

∴ Percentage increase of investment in Khammamin $1995-96 =  \dfrac{8352-7081.6}{7081.6} = \dfrac{1270.4}{7081.6} = 0.1793 \hspace{0.2cm}i.e. 17.93\%$

Now, in 1997 $\{ 8352 \times 17.93\% = 1497.5136 \hspace{0.1cm} Rs. \}$ extra will be given to Khammam District than 1996

So, total investment in $1997$ will be $(8352+1497.5136 =)Rs.  \hspace{0.1cm}9849.5136  \approx Rs. \hspace{0.1cm}9850$ 

∴ Answer will be Option A)
