Answers
Answer:
Two vessels A and B contain milk and water mixed in the ratio 8:5 and ... Most Helpful Expert Reply ... say A qty of vessel A and B qty of vessel B is added together.
If the percentage of milk is 31.25%, then 30 litres of milk should be added so that milk and water become equal.
Step-by-step explanation:
The quantity of a initial mixture of milk and water in the container = 80 litres
The percentage of milk = 31.25%
∴ The initial quantity of milk = 31.25% of 80 = 0.3125 * 80 = 25 litres
Let the milk to be added in the mixture be denoted as “x” litres.
So, the new quantity of milk will become = (25 + x) litres
And,
The new quantity of mixture = (80 + x) litres
Here, we want the final quantity of milk and water in the mixture to be equal, so we can write the final equation as,
50% of [new mixture] = [quantity of milk in the new mixture]
⇒ 50% of (80+x) = 25 + x
⇒ ½ * (80+x) = 25 + x
⇒ 80 + x = 50 + 2x
⇒ 2x – x = 80 – 50
⇒ x = 30
Thus, 30 litres more milk should be added so that milk and water become equal in the new mixture.
