I found this method quicker:
Let x amount of initial milk.
3/5x / 3/5(x+20) = 4/5
so x(initial) = 80
Present amount of milk = 3/5*80 = 48
Present amount of water = 3/5*(80+20) = 60
Present amount of orange = 2/5*(80+100) = 72
Milk + orange = 120.
SO we must take out 54.
In terms of percentage : (54/120)*100 = 45
