Hi,

I think this is the way how to solve this problem

Democractic : 55
Republican : 35
Total Eligible Population : x
Neither : 0.08x
(Its an election so you cant have both )

=> 55+35+0.08x = x
90 = 0.92 X
X = 100

Thus the percent of people eligible to vote actually voted in the elections = (55+35)/100 =>90/100 = 90%

Thus E


That's not correct.

If you are doing that way then you should have 55% + 35% + 0.08x% = 100%, because 55%, 35% and neither = 0.08x% together must sum up to 100% (all that voted). 55 + 35 + 0.08x = 100 --> x = 125 --> voted/eligible = 100/125 = 0.8.

Answer: C.

Let the Eligible number of voters = 100
Assume Actual number of people voted = x

55 + 35 = 90% of actual voters voted for either of the parties
—> 10% voted for neither
—> 10/100*x = 8 (Given)
—> x = 80

IMO Option C

Pls Hit kudos if you like the solution

Given:
1. In the presidential election, 55% of the people who voted, voted for the democratic candidate and 35% voted for the republican candidate.
2. 8% of the number of people eligible to vote, voted for neither the republican nor the democrat,

Asked: What percent of people eligible to vote actually voted in the elections?

Let the number of people eligible to vote be x
Let the number of people actually voted be y

55%y + 35%y + 8%x = 100%y
8%x = 10%y
y/x = 8%/10% = 80%

The percent of people eligible to vote actually voted in the elections = 80%

IMO C

Re: In the presidential election, 55% of the people who voted, voted for [#permalink]
Let total people eligible to vote= y
Total people voted= x
Democrats= 0.55 x
Republic= 0.35 x
Total= 0.9 X
Balance= 0.1 X..... These people didn't vote for both Democrats or Republicans

Now people who didn't vote for republic or Democrats are 0.08y.

So it means, 0.1 X = 0.08 Y hence X is 0.8 times Y which is 80% of Y.

Re: In the presidential election, 55% of the people who voted, voted for [#permalink]
Total# ppl eligible to vote = T

# of ppl who actually voted = V

The percentage of ppl who actually voted who voted neither for Democrats nor for republicans = 100% - (55%) - (35%) = 10%

And this is ———-> 10%(V)

“8% of the ppl eligible to vote did so for neither”

10%(V) = 8%(T)

“What percent of eligible voters actually voted?”

Or

What’s is: (V / T) * (100)% = ?


10%(V) = 8%(T)

V/T = 8/10 = 80/100 ———-> 80%

(C) 80%
