Question

In a jar there was 60 litres of pure milk 12 litres of milk was taken out and
replaced with equal amount of water. After that 15 litres of the new mixture
of milk and water was taken out and replaced with equal amount of water.
What is the respective ratio of milk and water in the container now?
1.9:8
2.5:2
3.7:6
4. 3:2
5.5:4​

Answer 1

Step-by-step explanation:

Firstly when the milk was replaced

the ratio became 48:12

and the second time the ratio became 45:15

but on the second replacement the solution had a mixture of both water and milk of 48:12 or 4:1

which means 4x+x=15

x=3

12 litres of milk and 3 litres of water got replaced

total milk= 60-12-12=36 l

and total water= 60 l -36 l= 24 l

therefore ratio = 36/24 = 3:2
