Question

the ratio of milk to water in a mixture is 3 : 2. if 1 litre of milk is added to the mixture then the new ratio becomes 2 : 1. what is the amount of milk in the new mixture? 1 point

Answer 1

Step-by-step explanation:

x/y=3/2

3y=2x

y=2x/3

x+1/y=2/1

2y=1.(x+1)

2y=x+1

2.(2x/3)=x+1

4x/3=x+1

4x=3.(x+1)

4x=3x+3

4x-3x=3

x= 3 Litre

adding : 3+1 = 4 litre (answer)
