• According to question,
  Quantity of Water = 10% of 50 = 5 liter.
  and, Milk = 45 liters
  Let x br the amount of water to be added.
  Now,
  => (5 + x) = 20% of (50 + x).
  => 5 + x = ( 50 + x ) / 5.
  => 25 + 5x = 50 + x
  => 4x = 25
  => x = 6.25 liter.
  
  So 6.25 litres should be added to make the mixture 20% watery ( ;-) )

• let add x ltr water to 50 ltr mixture
  then 20% water=5+x
  then, 50+x=5(5+x)
  =>x=6.25
