20% answer

Answer 2

Quantity of Milk = 20L

Quantity of water in milk = 10L

Both = (20+10)L

= 30L

Add 10L water to form new mixture = (30+10)L

= 40L

Amount of water in new mixture = 20L

Percentage of water in new mixture = x%

$x\% \: of \: 20 = 40 \\ 20x = 40 \\ x = \frac{40}{20} \\ x = 20\%$
