Jai won , 3000 on a bet, which meant he had five times more money than if he had lost $₹3000$. How much money had jai before he won the $₹3000$?

Let jai had money before be won the$₹3000=₹x$

According the question

$\begin{array}{l}x+3000=(x-3000)\times 5\\ \Rightarrow x+3000=5x-15,000\end{array}$

$\begin{array}{l}\Rightarrow 4x=18,000\\ \Rightarrow x=4500\end{array}$

So, jai had $₹4500$ before he won the $₹3000$
