Building,cost land cost Total $1,00,00,000 \\ 70,00,000 \\ 1,70,00,000 $
Net return $\frac{7}{100}\times17000000 \\ Total$ $1190000$
Sinking fund $I_c$ $=\dfrac{i}{(1+i)^n-1} \\ =\dfrac{0.09}{(1+0.09)^60-1} \\ I_c=5.14 \times 10^{-4} \\ \text{Sinking fund instalment} \\ =I_c \times (cost-scrap) \\ = 5.14 \times 10^{-4} \times (10000000-0.1 \times 10000000) \\ =4626$ -

$\text{Repair & maintenance cost}$ $= \dfrac{7}{100}×10000000 \\ = 700000$

$\text{Gross rent = Net rent + sinking fund + Annual maintenance + outgoings}$

$\hspace{1.5cm}x = 1190000 + 4626+ 700000+ 0.25 x$

Gross rent =2526168

$\text {Therefore Gross rent / month} = \dfrac{2526168}{12}=Rs.210514 \\ \text{Therefore Gross rent / month/flat} = \dfrac{210514}{20}=Rs.10526$
