Solution(By Apex Team)
$\begin{array}{l}
\text { Let total capital }=\text { Rs. } \mathrm{x} \\
\text { Then, A’s capital }=\text { Rs. } \frac{x}{3}
\end{array}$
B’s capital = (A + C)’s capital ⇒ 2(B’s capital)
B’s capital = (A + B + C)’s capital = Rs. x
$\begin{aligned}&\Rightarrow\text{ B’s capital }=\text{ Rs. }\frac{x}{2}\\
&\Rightarrow\text{ C’s capital }\\
&=\text{ Rs. }\left[x-\left(\frac{x}{3}+\frac{x}{2}\right)\right]\\
&=\text{ Rs. }\frac{x}{6}\\
&\therefore\text{ A }:B:C\\
&=\frac{x}{3}:\frac{x}{2}:\frac{x}{6}\\
&=2:3:1\\
&\text{ So C’s share }\\
&=\text{ Rs. }\left(900\times\frac{1}{6}\right)\\
&=\text{ Rs. }150\end{aligned}$
