Answer 2

Answer:

In the mixture of 20 Kg milk and water , 15 % is water . if 5 liters water is added to it , then the percentage of milk will be 68%.

Step-by-step explanation:

• 20 kg of a mixture contain 15% water and (100-15)= 85 % of milk.

• So, Quantity of water in the mixture =15% of 20 kg = $\frac{15}{100}$ × 20 = $\frac{15}{5}$ = 3 kg.
• Quantity of Milk in the mixture = 20 - 3 = 17 kg

• After adding 5 liters of water in the mixture now, the total amount of the mixture will be, 20+5 = 25 kg.
• Let the percentage of milk will be x%.

Hence , x% of 25 = 17 kg

⇒ $\frac{x}{100}$ × 25 = 17

⇒ $\frac{x}{4}$  = 17

⇒  x = (17 × 4)

⇒  x = 68

• Hence, if 5 liters water is added to the mixture , then the percentage of milk will be 68%.
