Question

In a 120 litre mixture of milk and water the percentage of water is only 20% of water

Answer 1

Answer:

Mixture = 120 litre, Water = 25%

Water = 25100×120 = 30 litre

And milk = 120 - 30 = 90 litre

After settling 20 litre of mixture, remaining mixture = 100 litre

In 100 litre of mixture, amount of milk and water will remain in the same percent.

Water = 25100×100 = 25 litre

And milk = 75 litre

Now, he added 16.2 litre of milk and 3.8 litre of water.

Milk = 75 + 16.2 = 91.2 litre

And water = 25 + 3.8 = 28.8 litre

Total new mixture = 120 litre

Required percentage = (28.8120×100)%

= 24%
