Election Votes Distribution

Let total casted votes be $V$. Candidate 1 receives $30\%$ of $V = 0.30 V$. Remaining votes = $70\%$ of $V = 0.70 V$. These are divided among Candidates 2, 3, 4 in ratio $1 : 2 : 3$. Shares: $\frac{1}{6} \times 70\% = 11.67\%$, $\frac{2}{6} \times 70\% = 23.33\%$, $\frac{3}{6} \times 70\% = 35\%$. So the votes percentages of the 4 candidates are $30\%, 11.67\%, 23.33\%, 35\%$. The winner receives $35\%$ of $V$. The second highest candidate receives $30\%$ of $V$. Difference = $35\% - 30\% = 5\%$ of $V = 2512$. $0.05 V = 2512 \implies V = 50240$. Since 80% of registered voters ($R$) casted votes: $0.80 R = 50240 \implies R = \frac{50240}{0.8} = 62800$.
