Answer 1

Answer:

The answer is 45%.

Explanation:

The two jars having a capacity of 3 litre and 5 litres respectively are filled with mixtures of milk and water.

As given in the smaller jar 25% of the mixture is milk and the larger jar has 25% of the mixture is water.

Amount of milk in the first jar= 3 x(25/100)= 3/4 ltr

Amount of milk in the second jar= 5 x(75/100)= 15/4 ltr

Now the jars are emptied into a 10 litre cask whose remaining capacity is filled up with water. So the percentage of milk in the cask should be

[{(3/4)+(15/4)}/10]x100

= {18/(4x10)}x100 %

= 45%
