Detailed Solution

$\begin{matrix} initial & final \\ 100 ml & 100 ml \\ P^{0} & P \end{matrix} \begin{matrix} initial & final \\ 150 ml & 150 ml \\ O & P \end{matrix}$

Total moles initially and finally is constant.

$∴ 100 \times P^{0} + O = 100 \times P + 150 \times P$

$\Rightarrow P \frac{100 \times P °}{250} = 40 % of P °$
