Answer 1

Answer:

Then the amount of milk in 20litres is 20*. 6=12 litres . Now 5 litres of milk is added to it. Hence the amount of mixture is 20+5=25 litres

I hope this will helpful

Answer 2

Question:-

A vessel has 20 litres of a mixture of milk and water having 60% milk. Five litres of pure milk is added to the vessel Find the percentage of milk in the new solution

• 70%
• 68%
• 64%
• 66%

Given:-

• A vessel has 20 litres of a mixture of milk and water having 60% milk.
• Five litres of pure milk is added to the vessel

To Find:-

• The percentage of milk in the new solution

Solution:-

Total volume of mixture in vessel = 20 litre

mixture percentage = 60%

$\sf\green{milk's \: volume \: = \frac{60}{100} \times 20 = 12 \: litre }$

Now 5 litre of pure milk added to the mixture again

Then the total volume of mixture = 25 litre

Volume of milk = 17 litre ( 12 + 5 )

$\sf\green{percentage \: of \: milk \: in \: new \: solution \: = \: \frac{17}{25} \times 100 } \\ \sf\pink{ = 68\%}$

Hence

• percentage of milk in new solution = 68%
