(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.

60% poltical party ppl= 0.6n

Toal votes received

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.

(B) 0.1N+7200
(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.
