A solution consists of only water and alcohol such that the ratio of a...

Step 1 & 2: Understand Question and Draw Inference

Given:

Ratio of alcohol to water in original solution = 7:3
Let the quantity of original solution be x ml.

To Find:

We have to find the quantity of water to be added to the solution, such that the resulting solution contains 60% of alcohol.
Let the quantity of water that is to be added to the solution be y millilitres.
So total quantity of final solution will be x+y millilitres
Now since only water is being added we can infer that the quantity of alcohol in the solution will not change.
So quantity of alcohol in the final solution will be
Percentage of alcohol in the final solution should be 60%

Since we do not know the value of x, we will not be able to determine the value of y.
So we need a relation in x and y, or value of x or y, to be able to determine the amount of water to be added to the solution.

Step 3 : Analyze Statement 1 independent

Total quantity of the resulting solution is 350ml.
Total quantity of the resulting solution = x+y ml (Already established above)

⇒ x+y=350ml ...(Equation 2)

Since we have another relation in x and y, we will be able to determine the value of y, and thus the amount of water to be added to the solution.
Hence statement 1 is sufficient to answer the question.

Step 4 : Analyze Statement 2 independent

The original solution contains 10.5ml of alcohol for every 4.5ml of water.
The ratio of alcohol to water from this statement comes out to be 7:3, which is the same as given to us in the question stem.
So we do not get any additional information from which we can determine the values of x or y.
Hence statement 2 is not sufficient to answer the question.

Step 5: Analyze Both Statements Together (if needed)

Since from statement 1, we are able to arrive at a unique answer, combining and analysing statements together is not required.
Hence the correct answer is option A
