If the statements made by the Spokesperson are true, then which of the following must be true?

A. At least half of the female voters supported the incumbent mayor
.
B. The incumbent mayor received stronger support from the female voters than from the male voters.

C. were no other candidates in the election who received more than 30% of all the votes.

D.Less than half of the voters in the election were male and all of them were either 70 years or younger .

E. If the proportion of male and female voters in the city remains the same, the incumbent mayor is also likely to win the next election.


OE:

This argument essentially asks us to find a conclusion that must be true based on the facts presented by the spokesperson. When you analyze the answer choices, remember that the correct answer to questions of this type must be the claim that does not require any additional assumptions.

(A) This statement does not have to be true, since the female voters represented only slightly more than a half of the electorate. For example, the mayor would be able to receive 2/3 of all voters if he received all the votes of the male voters (i.e. 45%) and just some substantial portion of the female voters (say 40%).

(B) This statement does not have to be true. For example, the incumbent mayor could have received the vast majority of the male votes and a smaller share of the female votes.

(C) Since the incumbent mayor received 2/3 (i.e. approximately 67%) of the votes, the maximum number of votes received by any other candidate could have been around 33%, which is still substantially less than the number of votes received by the incumbent mayor. Since we do not know how many candidates participated in the election and the proportion of votes received by each candidate, we cannot conclude that no other candidate received more than 30% of all votes.


(D) CORRECT. Since 55% of the voters were female, the remaining 45% were male; also, since all the voters were between ages 18 and 70, no voters, either male or female, could have been more than 70 .

(E) Even if the proportion of the male and female voters remains the same, their preferences may change substantially and there is no guarantee that they will vote in the same way in the next election.

D for me.

If the statements made by the Spokesperson are true, then which of the following must be true?
a.At least 1/2 of the female voters supported the incumbent mayor. <-- not necessarily true. If there were 100 voters then 66 voted for mayor. All of the remaining 34 could be female and that means less then 1/2 of females voted for mayor.

b.The incumbent mayor received stronger support from the female voters than from the male voters. <-- Again not necessarily true similar reasoning as A

c.There were no other candidates in the election who received more than 30% of all the votes. <-- We dont know how many candidates there are. There could be just 2 candidates and the other one could have received 34 votes.

d.45% of the voters in the election were male and none of them were 75 years old. <-- bingo if 55% are female, then 45 are male. Since no one is above 70, no ones above 75 either.

e.If the proportion of male and female voters in the city remains the same, the incumbent mayor is also likely to win the next election. <-- rather silly statement if you ask me.

Please explain your response....thanks in advance

cheers!

i was sweatin when i read this q ... but quickly and luckily found D

Its the one that you can find support for in the passage very easily ... we are told 55% of voters are women, so 45% must be men ... and we are told ALL voters are btwn 18 and 70, so no one can be 75, male or female.

lesson learnt ..attention to detail.
I never saw '75' in D. I thought (blindly) it was 70 and started searching for answer. Never made it.
Thanks simple but good one.

A little arithmetic will do the trick here.
Let total voters=100
Females=55;Males=45
Supported=67;Didnt support=33

Option A.If all males supported,female supporters=67-45=22 not half of 55.Incorrect.

Option B.the above case can prove this point also;males=45;females=22.Incorrect.
C-what if there were only 2 candidates and the other recd.the rest ie 33?

D-given in the stem itself.Correct.

E-nothing about the future can be absolutely true.

D is the answer. 55% were female --> 45% were male, all voters were b/w 18 & 70 --> none of them were 75

It's best to solve this question by taking some numbers -


Let No of Voters in the age group of 18 -20 Years be 300
Female Voters is 165
Male Voters is 135

2/3rd of the Voters support the incumbent Mayor, so 200 voters supported the mayor and are likely to vote in favor of him. ( Assuming all eligible voters cast their votes)
So, The Mayor didn't get 1/3rd of the total Votes , ie 100 votes and won the election by a substantially greater number of votes than any other candidate.

We can say the Winner got 66.67% of the total votes and the other candidates got 33.33% of the total votes cast.


Among the options presented (D) directly flows from the stimulus ( Highlighted parts of the stimulus )

1. 55% of the voters were female = 45% of the voters were male
2. All the voters were between ages 18 and 70 = All the voters were less than 75 Years age.

Remember for a must be true type question PowerScore CR states -

1. Paraphrase / Restate what has already been presented in the stimulus.
2. Results from a combination of 2 or More statements presented in the stimulus.


Thus correct answer is (D)

How can one say that if Females are 55% then Males must be 45% ?
This is not always possible. May be there are some Trasngender ?

yes, OA is D b/c using POE, D is left.
This man is a retired gmat counselor who worked at Kaplan many years ago. This time, I have no idea why the expert posts a question whose source is unclear.
Anyway, I still appreciate his effort in explaining the solution in detail.

Test takers can learn much from this expert.
