Question

90 ltr. Milk contains 8% fat. How many litres of pure water should be added to it so that the fat percentage of diluted milk will be 6%?
1) 45 ltr.
2) 22.5 ltr.
3) 60 ltr.
4) 30 ltr.​

Answer 1

Answer:

30 litres.

Step-by-step explanation:

Let,

water be 'x'

ATQ,

8% of 90 + 0% of x = 6% of (90+x)

720/100 = (540+6x)/100

6x = 720-540

x= 180/6

x= 30

So,30 liters of water should be added.
