Milk with water 2

If 50 liters of a mixture contains milk and water in a ratio of 3:2, how much milk must be added to the mixture to have milk and water in a ratio of 9:4?

Correct answer:

m =  15 l

Step-by-step explanation:

V=50 l r1=3:2=1.5 r2=9:4=2.25  x:(Vx)=r1  x=r1 (Vx) x=1.5 (50x)  2.5x=75  x=2.575=30  x=30  (x+m):(Vx)=r2  (x+m)=r2 (Vx) (30+m)=2.25 (5030)  m=15  m=115=15  m=15=15 l
