let the total registered voters be x
given that 30% did not cast their votes =0.3 x.
so therefore no of voters who cast the votes = x-0.3 x = 0.7 x
so given that no of winner got ,W= Looser + 684
so therefore , W-L=684
Also given winner votes is 42% of registered voters,W = 0.42 x
NO OF INVALID VOTES= 180
nof cast votes, 0.7 x = W+L+Invalid votes
0.7x= L+684+L+180
0.7X = 2L+864
0.7x=2(0.42x-684)+864 (solve this equation)
0.14x= 504
x= 3600
no of registerd voters= 3600

As the electorate expanded, the political parties evolved to mobilize the growing mass of voters as the means of political control. ... In recent decades, increasing numbers of individual voters classify themselves as “independent,” and they are permitted to register to vote as such in many states.
