(B) .1N+7200
(C) .4N+7200
(D) .1N+8000
(E) .06N+8000


40% of N are independent voters, hence 60% of N are not independent voters. From this group she received 10% votes so, 0.1*0.6*N plus 8,000 votes from independents: total=0.1*0.6*N+8,000=0.06*N+8,000.

Answer: E.

40% independent voters= 0.4n
60% poltical party ppl= 0.6n

Toal votes received
= 8000 + 10% of .06n
= 8000 + 0.1*0.6*n
=8000 + 0.06n

Wordings is quite poor as the question does not state that Robinson received 100% of the votes cast by independent voters i.e. 0.4N = 8000.

Answer is E

Let X be the Total Number of Votes received by Ms. Robinson.

In which 8000 votes cast by independent voters + 10 percent of the votes cast by voters registered with a political party

According to question, N is the total number of votes cast in the election and 40 percent of the votes cast were cast by independent voters

So, X = 8000 + 10% of (100-40)%N

X = 8000 + 0.06 N

Total no. of vote = N.
Therefore,Mrs Robinson received : .60*N*.10 +8000 = .06N+8000.
The ans. is E

Where is my reasoning incorrect. Please advise:

Given:
8000 votes by independent
10% votes of total not independent
40% votes from N (total) = independent voters

My solution 1:
8000 + 0.10(N - 8000)
8000 + 0.10N - 800
0.10N + 7,200

Why is this incorrect?

Solution 2:
8000/0.40 = 20,000
IV = 8000
Not IV = 12000 * 0.10 = 1200
8000 + 1200 = 9200 (total votes Ms. Robbins received)

Checking the answers by plugging in 20000 for N:
A - out
B - correct
C - out
D - out
E - correct

B or E, from solution 1 I chose B?

Please advise,

Thank you

The highlighted part is not correct. The number of registered voters is not N - 8000, because the number of independent voters is not 8000. 8000 is the number of independent voters received by Ms. Robinson.

(C) 0.4N+7200
(D) 0.1N+8000
(E) 0.06N+8000


We are given that Ms. Robinson received 8,000 votes cast by independent voters and 10% of the votes cast by voters affiliated with a party.

Since N is the total number of votes and 40% of the votes were cast by independent voters, 60% of the votes were cast by voters affiliated with a party.

Since Ms. Robinson received 10% of the votes cast by voters affiliated with a party, she received (0.1)(0.6)N = 0.06N of the votes by voters who are affiliated with a party. Since she also received 8,000 votes from independent voters, she received 0.06N + 8,000 total votes.

Answer: E

After putting the value of N(20,000) in the equations, both B and E are correct. So, how to choose the correct option.

Hi All,

This question can actually be answered with just a little logic (no real calculations are required).

From the first sentence, we know that Ms. Robbins received 8,000 votes; and from the second sentence, we know she received 10% of the votes from voters registered with a political party. We're told that N is the TOTAL number of votes cast. Since the 10% that were mentioned was NOT 10% of the total votes, the remaining votes that Ms. Robbins received CANNOT be described as .1N (it has to be something LESS than .1N). There's only one answer that matches.

Final Answer:

GMAT assassins aren't born, they're made,

The assumption that you made here is that others didn't receive any independent voters vote . Hence we can't conclude that 0.4*N=8000 .

I did the same mistake while solving initially .

Hope it clarifies the doubt.

Hence answer E is the only correct answer
