In the presidential election, 55% of the people who voted, voted for the democratic candidate and 35% voted for the republican candidate. If 8% of the number of people eligible to vote, voted for neither the republican nor the democrat, what percent of people eligible to vote actually voted in the elections? | [
"90",
"80",
"88",
"40"
] | B | let people eligible to vote = y
people actually voted = x
Democratic = 0.55x
Republican = 0.35 x
total voters = 0.90 x
hence 0.10x voters who voted didnt voted for D and R.
now, 0.10 x = 0.08 y
=> x/y = 8/10
hence 80%
