1Rs. 105000
2Rs. 111500
3Rs. 123000
4None of these

Answer:- 1

Explanation:-

Solution:

\begin{aligned} Subhas : Aditya \\ = (25000 \times 36) : (15000 \times 6 + 30000 \times 24) \\ = 900000 : 810000 \\ = 10 : 9 \\ ∴ Aditya's share \\ \Rightarrow Rs . (247000 \times \frac{9}{19}) \\ \Rightarrow Rs .117000 \end{aligned}

$\eqalign{ & {\text{Subhas}}:{\text{Aditya}} \cr & = \left( {25000 \times 36} \right):\left( {15000 \times 6 + 30000 \times 24} \right) \cr & = 900000:810000 \cr & = 10:9 \cr & \therefore {\text{Aditya's share}} \cr & \Rightarrow {\text{Rs}}{\text{.}}\left( {247000 \times \frac{9}{{19}}} \right) \cr & \Rightarrow {\text{Rs}}{\text{.117000}} \cr}$
