Answer 1

Explanation-

Mixture given = 40L

10% of which was water. So remaining 90% was milk.

Now we have to increase the water percentage to 20%. Therefore the milk percentage in new mixture is 80%. In ratio, it becomes 4:1.

Lets say we added ‘x’ litres of water in the mixture and quantity of milk remains constant throughout.

So, x=5L of water must be added in the mixture to make water 20% in new mixture.
