### Solution(By Apex Team)

\begin{array}{l}\text{ Let the total profit be }Rs.Z\\ \begin{aligned}\text{ Bharti’s share }&=\frac{2}{3}Z\\ \text{ Rahul’s share }&=Z-\frac{2}{3}Z\\ &=\frac{Z}{3}\end{aligned}\end{array} \begin{aligned}&\text{ Rahul:Bharti }\\ &=\frac{Z}{3}:\frac{2}{3}Z=1:2\end{aligned} \begin{aligned}&\text{Now let the total capital be Rs X,}\\ &\text{and Bharti capital was used for Y months.}\\ &\text{then, Rahul capital will be}\ \frac{1}{4}X\\ &\text{and Bharati CApital will be}\ \left(X-\frac{1}{4}X\right)\\ &=\frac{3X}{4}\\ &\Rightarrow\frac{\frac{1}{4}X\times15}{\frac{3}{4}X\times Y}=\frac{1}{2}\\ &\therefore\text{Y}=\frac{15\times2}{3}=10\end{aligned} So, Bharati’s money was used for 10 months
