Answer 2

Answer:

Percentage of water added = 16.66%.

Step-by-step explanation:

In the question,

The mixture of milk and water has 40% water.

So,

Let us say that there is '100x' litre of mixture.

So,

Amount of water = 40x

and,

Amount of Milk = 60x

Now,

Let us say that 'y' litre of water is added to make the ratio 1:1.

So,

$\frac{40x+y}{60x}=1\\ So,\\y=60x-40x=20x$

Therefore, the amount of water added is 20x.

Or we can also say that,

$\frac{20x}{100x+y}\times 100=Percent\ of \ water\ added\\ Percent\ of \ water\ added=\frac{20x}{100x+20x}\times 100\\ Percent\ of \ water\ added=\frac{20x}{120x}\times 100=16.66\%$

Therefore, the percentage of water added is 16.66%.
