9 litres are drawn from a cask full of water and filled with mik.9 litres of mixture are drawn and again filled with milk.now the quzntity of milk to that wzter in the cask is 16:9.how much mixture does the cask hold?

• Ans: 45
  16/25=(x(1-9/x)^2)/x
  16/25=((x-9)/x)^2
  4/5=x-9/x
  x=45

• let total amt of water = x
  9 litres of mixture are drawn
  so now water = x-9
  milk added = 9
  now the quzntity of milk to that wzter in the cask is 16:9
  (9/(x-9)) = 16/9
  x = 14(approx)

• Ans:22.5
  Water left=((x-9)^2/x)=w
  9/25=w/x
  Calculate
  X=22.5
