When 2/9 of the votes on a certain resolution have been counted, 3/4 of thoes counted are in favor of the resolution. What fraction of the remaining votes must be against the resolution so that the total count will result in a vote of 2 to 1 against the resolution?

When 2/9 of the votes on a certain resolution have been counted, 3/4 of thoes counted are in favor of the resolution. What fraction of the remaining votes must be against the resolution so that the total count will result in a vote of 2 to 1 against the resolution?

A. 11/14 B. 13/18 C. 4/7 D. 3/7 E. 3/14

If we use variable for total votes there will be too many fractions to manipulate with, so pick some smart #: let set total # of votes is 18.

"2/9 of the votes on a certain resolution have been counted" --> 4 counted and 18-4=14 votes left to be counted; "3/4 of those counted are in favor of the resolution" --> 3 in favor and 1 against;

Ratio of those who voted against to those who voted for to be 2 to 1 there should be total of 18*2/3=12 people who voted against, so in the remaining 14 votes there should be 12-1=11 people who voted against. Thus 11/14 of the remaining votes must be against.

Answer: A.

Did in the same way, just created a table as below

Let's say there were 90 votes. 2/9 Votes = 20 Out of 20 3/4 in favour = 15 and remaining against = 5

For 2:1 against to favour ratio out of 90 votes= 30:60 Mores votes needed against = 60 - 5 = 55 Remaining votes = 90-20 = 70

A. 11/14 B. 13/18 C. 4/7 D. 3/7 E. 3/14

Solution:

Lets use the plug in method to solve this question.

The question states that 2/9th of the votes are counted 3/4th are in favour of the resolution. Lets take a value for the the total number of votes. While we can take any value its smart to take a value which is a multiple of 9 as we know that the first part of the question says 2/9th of the votes are counted. Lets assume the total number of votes = 18.

Part 1 : 2/9 of the votes are counted = 2/9*18 = 4. It further states that 3/4 of the counted votes are in favour, which means 3/4*4 = 3 are in favour.

The question is asking what number of the remaining votes should be against the resolution such that we get a final count of 2:1 against the resolution.

Part 2: Which means: we need 2/3*18 = 12 votes against the resolution. We know from part 1 that 1 vote is against the resolution out of a total of 4 counted votes. Therefore we need another 11 votes out of a remaining (18-4) votes to be against the resolution to get a final ratio of 2:1.

Therefore the ratio of votes which need to be against the reolution out of the remaining votes will be = 11/14.

Thus, Answer is A.

Tip - It makes more sense to plug in a value for total number of votes rather than solving it in fraction form as it simplifies calculations.

A. 11/14 B. 13/18 C. 4/7 D. 3/7 E. 3/14

Based on the denominators in the fractions 2/9 and 3/4, let us assume there are 36 votes.

2/9 are counted i.e., 8 counted out of 36 3/4 of counted in favor i.e, 6 are in favor and 2 are against out of 8 counted Against given 2 to 1 i.e, 24 to 12 against out of 36 Remaining against = 24-2=22 Remaining Votes :28 Answer is 22/28=11/14

Let the total number of voters be 36 ( LCM of the denominators 4 & 9)

Total number of votes counted is (2/9*36) = 8 Total number of votes not counted is ( 36-8) = 28

Total number of voters in favour of the resolution whose votes have been counted is (8*3/4) =6 Total number of voters against whose votes have been counted is (8-6) = 2

Total number of votes required for 2 : 1 against the vote is = 36*2/3 =>24

Out of 24 total votes we already have 2 votes against the resolution so out of the remainin 28 votes ( which have not been counted) we required 24 votes.

So, The effective percentage of votes required is 22/28 =>11/14

Hence Answer is (A) _________________
