Answer 1

30 liters of pure milk is required to increase the percentage of pure milk to 80%.

Step-by-step explanation:

Total amount of solution = 20 liters

The percentage of pure milk is 50%.

Amount of milk in the solution =$50\% \times 20 = \frac{50}{100} \times$20 = 10/50%×20=

100/50 ×20=10

Let x be the amount of pure milk is required to increase the percentage of pure milk to 80%

So, new Amount of milk = 10+x

ATQ

10+x=80%×(20+x)

10+x=$\frac{80}{100}\times$ (20+x)10+x= 100/80×(20+x)

10+x=0.8(20+x)10+x=0.8(20+x)

10+x=16+0.8x10+x=16+0.8x

0.2x=60.2x=6

x=30x=30

Hence 30 liters of pure milk is required to increase the percentage of pure milk to 80%.
