A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.



Given

A=2, B =5

2+X/ 5+Y = 1/2

(1) says X=2/3Y

2 eq's 2 unknowns. Solve for x to get the answer. Suff

(2) says X +Y =5

2 eq's 2 unknowns. Solve for x to get the answer. Suff

I thought the answer should be C.

In case of statement 1, we can have multiple values of banana and apple. There can be 5 apples and 10 banana thus adding 3 apples and 5 bananas and there can also be 10 apples and 20 bananas giving ratio of 1/2 but apples added will be 8 and 15 banana.

Can someone clarify if I am missing something?

If A apples were added and B bananas were added:
(2+A)/(5+B)=1/2
Statement 1: is telling 2 bananas were added for every 3 apple added. i. e. A=2/3 B . plugging the value of B we can solve for A.
Statement 2: A+B=5. similar as statement 1. can solve for A.

D.

Isn't (1) saying the # of apples to bananas is 2:3? So for every 2 apples, there are 3 bananas? Couldn't it be 4 to 6, 6 to 9, etc? We can't get an exact amount of apples that were added from this like this question is asking for.

(2) is clearly sufficient, but I'm having issues with (1).

Well the way I look at this question is that there are two unknowns.

Number of apples added = x
Number of bananas added = y

If we have two different equation, we can find unique values of x & y

One equation can be made using the information in question => (2+x)/(5+y) = 1/2

Argument 1 gives us another equation => x = 2/3y
If you put x = 2/3y in first equation you will get a unique solution.
So, it is sufficient.

Argument 2 also gives us on equation => x+y = 5
Again a unique solution is possible. It
So, it is sufficient.

Hence, the answer is D.

Whatever value you take, the ratio remains same and so our answer also. By taking 4/6 you are taking extra 2 multiplied in both numerator and denominator, so whatever you take 4/6 or 6/9 or 8/12 answer will always be same.

If you add 4 apples and 6 bananas then you have 6 apples and 11 bananas which isn't a ratio of 1:2.
Only 2 apples + 3 banans lead to a total of 4 apples and 8 bananas -> Ratio of 1:2. No other multiple of 2:3 would lead to a total ration of 1:2.

Therefore (1) is sufficient as we get a clear # value for apples and bananas.

There were 2 apples and 5 bananas in a basket. After additional apples and bananas were placed in the basket, the ratio of the number of apples to the number of bananas was 1/2. How many apples were added?

From the stem: \(\frac{2+a}{5+b}=\frac{1}{2}\)]

(2) A total of 5 apples and bananas were added --> \(a+b=5\).

Solve these two equations to get a=2 and b=3.

(1) The number of apples added was 2/3 the number of bananas added.
(2) A total of 5 apples and bananas were added.


(2+A) / (5+B) = 1/2

4+2A = 5+B
2A = 1+B

The goal is to find A.

Statement 1) A = 2/3*B

2A = 1+B
A = 2B/3

3A = 2B
4A = 2+2B
-A = -2
A = 2
B = 3

Sufficient.

Statement 2) A+B = 5

A+B = 5
2A = 1+B

A = 5-B

2(5-B) = 1+B
10-2B = 1+B
9 = 3B
3=B
2=5

Sufficient.
