I think it is D but am not sure as I am confused with the question.
At one point it says that 40% said they had received scholarships. Then point (1) states that 25% surveyed said they had received scholarships.
Can anyone explain this?

I think (D) as well.

30% of student had loans
40% of student had scholarships

1) 25% of students said to have recieved scholarships only
Which means :
> 40 - 25 = 15 % recieved scholarships + loans
> 30 - 15 = 15 % recieved loans only

Thus : 100 - (15+25+15) = 45 % that recieved neither loans nor scholarships

>> Sufficient

2) 50% = 1/2 of students who recieved loans claimed to recieve scholarships
So :
> 30 / 2 = 15 % recieved loans & scholarships
> the other 15% got loans only
> 40 - 15 = 25 % recieved scholarships only

Thus : 100 - (15+25+15) = 45 % that recieved neither loans nor scholarships

>> Sufficient

The answer is D

only Scholarship : S
only Loan : L
Scholarship & Loand : B

S+L = 80 students
B+L = 60 students

from this we know that S+B+L+L = 140

To find out those received neither S nor L, we have to figure out
200 - S - B- L = 200 - (S+B+L)

all we need to know is the number of L. Also we can find out L once we know S or B.

both 1) and 2) seperately tell us one of these i.e. L or S or B

so that D is the answer.

St1:
Using a venn diagram, we can work out:
(% who had both scholarships and loans) = 15%
(% who had only scholarship) = 25%
(% who had only loans) = 15%

(% who had neither) = 100 - 25 - 30 = 45%

Sufficient.

St2:
(% who had both scholarships and loans) = 15% <-- 1/2 of those who received loans also received scholarship
(% who had only scholarship) = 25%
(% who had only loans) = 15%

(% who had neither) = 100 - 25 - 30 = 45%

Sufficient.

D.
Statement 1 is sufficient: 40% said that they had received loans, 25% said that they had received only scholarships. 40-15=25 is the % of students who received both S+L. Neither S, nor L= 100-15-25-15=45
Statement 2 is sufficient: 30%*05=15, or 15% of graduates received both loans and scholarships. Hence, only loans – 15%, only scholarships – 25%, and both 15%. Neither loan, nor scholarships= 100-15-15-25=45.

Total 200
n(L) = 0.3*200 = 60
n(S) = 0.4*200 = 80
n(not LnS)= Total - n(L)-n(S)+n(LnS)

S1. n(S-L) = 0.25*200 = 50 = n(S)-n(LnS)
n(not LnS)= 200 - 60 - 50 = 90
Thus, (90/200)*100 = 45%

S2. n(LnS) = 30
n(not LnS)= 200 - 60 - 80 + 30 = 90
Thus, (90/200)*100 = 45%

Hence, D.

50 percent of those surveyed who said that they had received loans also said that they had received scholarships

number of ppl. who received loans = 60
among those(60) 50% also received scholarships.
Thus those who received loans and scholarships = 30
Total = 200
200 = 60+80 -30 + X(those who received neither student loans nor scholarships)
X = 200 - 110 = 90.

Based on the information given, we can deduce that 60 graduates had received a loan and 80 graduates had received a scholarship.

Both options alone will help us find the answer so the answer is D.

(2) 50 percent of those surveyed who said that they had received loans also said that they had received scholarships.

30 percent received student loans --> 200*0.3=60 graduates received loans;

200={loans}+{scholarships} - {both}+{neither} --> 200=60+80-{both}+{neither} --> {neither}=60+{both}. Question: {neither}=?

As {neither}=60+{both} then we should calculate # of students who received both loans and scholarships.

(1) 25 percent of those surveyed said that they had received scholarships but no loans --> {scholarships} - {both}=80 - {both}=0.25*200=50 --> {both}=80-50=30 --> {neither}=60+{both}=60+30=90. Sufficient.

(2) 50 percent of those surveyed who said that they had received loans also said that they had received scholarships --> 0.5*{loans}={both} --> 0.5*60=30={both} --> {neither}=60+{both}=60+30=90. Sufficient.

(1) 25 percent of those surveyed said that they had received scholarships but no loans.
(2) 50 percent of those surveyed who said that they had received loans also said that they had received scholarships.

Solution:

The easiest way to solve this problem is to set up a double set matrix. In our matrix we have two main categories: student loans and scholarships. More specifically, our table will be labeled with:

1) Received student loans (Loans)

2) Did not receive student loans (No Loans)

3) Received a Scholarship (Scholarship)

4) Did not receive a scholarship (No Scholarship)

(To save room on our table headings, we will use the abbreviations for these categories)

We are given that there are a total of 200 college graduates in the survey. We also are given that 30 percent of those graduates received student loans and 40 percent received scholarships.

Thus,

200 x 0.3 = 60 received student loans

200 x 0.4 = 80 received scholarships

We are trying to determine what percent of those surveyed said that they had received neither student loans nor scholarships.

Let’s fill all this information into a table. Note that each row sums to create a row total, and each column sums to create a column total. These totals also sum to give us the grand total, designated by 200 at the bottom right of the table.

Statement One Alone:

25 percent of those surveyed said that they had received scholarships but no loans.

Using statement one we can determine the number of students who received scholarships but no loans.

200 x 0.25 = 50 students who received scholarships but no loans.

We can fill the above information into our table.

Thus, the percent of those surveyed who said that they had received neither student loans nor scholarships is (90/200) x 100 = 45%. Statement one is sufficient to answer the question. We can eliminate answer choices B, C, and E.

Statement Two Alone:

50 percent of those surveyed who said that they had received loans also said that they had received scholarships.

We are given that 50 percent of those surveyed who said they had received loans also said that they had received scholarships. From the given information we know that 60 students received loans; thus, we can determine the number of these 60 students who also received scholarships.

60 x 0.5 = 30 students who received loans who also received scholarships

We can fill the above information into our table.

Thus, the percent of those surveyed who said that they had received neither student loans nor scholarships is (90/200) x 100 = 45%. Statement two is sufficient to answer the question.

The answer is D
