CAT 2022 Slot 2 Paper

Let the number of registered votes be $100\mathrm{x}$
The number of votes casted $=80\mathit{x}$
Votes received by one of the candidates $=\frac{30}{100}\times 80\mathit{x}=24\mathit{x}$
Remaining votes $=80\mathit{x}-24\mathit{x}=56\mathit{x}$
Votes received by other three candidates is $\frac{56\mathit{x}}{6},\frac{2\times 56\mathit{x}}{6},\frac{3\times 56\mathit{x}}{6}$
It is given,
$28\mathit{x}-24\mathit{x}=2512$
$4\mathit{x}=2512$
$\mathit{x}=628$
The number of registered votes $=100\mathit{x}=62800$
The answer is option D.
