### Solution(By Apex Team)

Total capital invested by A in 1 year $\begin{array}{l} =12 \times 4000 \\ =\text { Rs. } 48000 \end{array}$ Total capital invested by B in 1 year $\begin{array}{l} =4 \times 6000+8 \times 8000 \\ =24000+64000 \\ =\text { Rs. } 88000 \end{array}$ Total capital invested by C in 1 year $\begin{array}{l} =9 \times 8000+3 \times 6000 \\ =72000+18000 \\ =\text { Rs. } 90000 \end{array}$ $\begin{array}{ccc}&\text{ A}&:&\text{B}&:&\text{C}\\ \text{ Capital}\longrightarrow&48000&:&88000&:&90000\\ &24&:&44&:&45\end{array}$ According to the question, \begin{array}{l}\begin{array}{l}(24+44+45)\text{ units }=\text{ Rs. }16950\\ 113\text{ units }=\text{ Rs. }16950\\ 1\text{ unit }=\frac{16950}{113}=\text{ Rs. }150\end{array}\\ \text{ Hence, }\\ \text{ Profit of }\mathrm{A}=150\times24\\ \begin{aligned}&=\text{ Rs. }3600\\ \text{ Profit of }\mathrm{B}&=150\times44\\ &=\mathrm{Rs}.6600\\ \text{ Profit of }\mathrm{C}&=150\times45\\ &=\mathrm{Rs}.6750\end{aligned}\end{array}
