If we mix the alcohol solution we have with pure water at the ratio 3: 2, we will obtain a solution of 18% alcohol. if we instead mix them at a ratio of 4: 1, what will be the alcohol percentage of the solution?

9%

Step-by-step explanation:

Let us assume that the original alcohol solution is x%.

So, when water and x% alcohol solution are mixed in the ratio 3 : 2, we will obtain a solution of 18% alcohol.

If water and x% alcohol solution are mixed in amount 3a and 2a amount, then we can write the equation as  

⇒

⇒ x = 45%

Now, water and 45% solution of alcohol are mixed in the ratio of 4 : 1, then the % of resulting alcohol solution will be
