### Solution(By Apex Team)

Let A’s capital = Rs. x Let B’s capital = Rs. y Now, according to the question, $\begin{array}{rlr}A&&B\\ \text{ Capital }\rightarrow x&&y\\ \text{ Time (in month) }\rightarrow(9+1)=10&&9\\ \text{ Ratio of profit }\rightarrow5&&6\end{array}$ $\begin{array}{l}\text{ We know, }\\ \Large\frac{10\times x}{x\times y}=\frac{5}{6}\\ \Leftrightarrow\Large\frac{x}{y}=\frac{3}{4}\end{array}$ Hence the required ratio of capital of A and B is = 3 : 4
