Given that, $\text{P: Q : R : S} = 5:2:4:3$
Let,
- $\text{P} = 5k$
- $\text{Q} = 2k$
- $\text{R} = 4k$
- $\text{S} = 3k$
Now, $\text{R} = \text{S} + 1000$
$\Rightarrow 4k = 3k + 1000$
$\Rightarrow {\color{Blue}{\boxed{k = 1000}}}$
$\therefore$ The share of $\text{Q} = 2k = 2(1000) = \text{₹}\;2000.$
$\textbf{Short Method:}$
$\text{P: Q : R : S} = 5:2:\underbrace{4:3}_{1}$
Now,
- $1 \longrightarrow \text{₹}\;1000$
- $2 \longrightarrow \text{₹}\;2000$
Correct Answer $:\text{D}$
