Hi chetan2u,
Could you please explain this question?
Thanking you.


types of people..
1) Did not vote......d
2) voted for..........f
3) voted against...a

we are looking for \(\frac{a}{(d+f+a)}\)

(1) 1/4 of the members of the legislature did not vote on the measure.
so\(d=\frac{t}{4}=\frac{(d+f+a)}{4}........4d=d+f+a......f+a=3d\)
nothing much
insuff

(2) If 5 additional members of the legislature had voted against the measure, then the fraction of members of the legislature voting against the measure would have been 1/3
now a becomes a+5
so \(\frac{a+5}{d+f+a}=\frac{1}{3}........3a+15=d+f+a.......2a+15=d+f\)
insuff

combined
three variables, two equation.. ans not possible
insuff

NEW question from GMAT® Quantitative Review 2019

We have two options here ON & OFF.

Employees can VOTE ON or VOTE AGAINST. Total #employees=voted ON+Voted AGAINST

Question stem:- # employees VOTE AGAINST=?

St1:- 1/4 of the members of the legislature did not vote on the measure.
Total # of employees is not provided. We can't determine # employees VOTE AGAINST.
Insufficient.

St2:-If 5 additional members of the legislature had voted against the measure, then the fraction of members of the legislature voting against the measure would have been 1/3
Here, neither #employees voted ON nor total #of employees is provided.
So, insufficient.

Combining, let total#of employees be x.
from st(1), we have , #of employees voted AGAINST=\(\frac{x}{4}\)
From st(2), we have, \(\frac{\frac{x+5}{4}+5}{x+5}\)=\(\frac{1}{3}\)
We can determine x, hence \(\frac{x+5}{4}\) can be determined.
Note:- \(\frac{x+5}{4}\) is the # employees VOTE AGAINST.
No need of exact computation.

Ans. (C)

Hi,

Take care that Statement 1 talks about No voting. It was not about voters against the measure.

nothing much

now a becomes a+5
so \(\frac{a+5}{d+f+a}=\frac{1}{3}........3a+15=d+f+a.......2a+15=d+f\)
insuff

combined
three variables, two equation.. ans not possible
insuff

E


In statement 2, when 5 additional members were added to 'a', Doesn't the total member become a+5+d+f ?

No,

5 is already part of total, they could be initially part of NOT voted or voted for
total will remain the same..
5 additional members of the legislature.. so they are part of total, just shifting sides

Statements combined:

Case 1: Total members = 24
Non-voters = \(\frac{1}{4} * 24 = 6\)
Since \(\frac{1}{3} * 24 = 8\), 5 additional members would bring the number who voted against the measure to 8, implying that 3 members actually voted against the measure.


Case 2: Total members = 48
Non-voters = \(\frac{1}{4} * 48 = 12\)
Since \(\frac{1}{3} * 48 = 16\), 5 additional members would bring the number who voted against the measure to 16, implying that 11 members actually voted against the measure.


Since the number who voted against can be different values, the two statements combined are INSUFFICIENT.
