To answer this question, let's match up the percentages of water in the two milk mixtures with the ratio that we want to achieve.

The ratio that we want to achieve is 3:5, water to milk.

So, we want 3/8 water and 5/8 milk.

To answer the question, let's focus on the water, since, if 3/8 of the mixture is water, the other 5/8 will have be milk.

The mixes that we have are 25% water and 50% water. Let's express them in 8ths as well.

The first mix is 2/8 water. The second mix is 4/8 water.

We want 3/8 water, and since 3/8 is halfway between 2/8 and 4/8, this question is turning out to be pretty easy.

By using allegation, we can determine that we have to use equal quantities of the two mixtures.

The correct answer is (B).
