  • A. 83.33 ml

  • D. can't be determined

  • Correct Answer
  • 83.33 ml 

    Explanation

    Profit (%) = 9.09 % = 1/11

     

    Since the ratio of water and milk is  1 : 11,

     

    Therefore the ratio of water is to mixture = 1:12

     

    Thus the quantity of water in mixture of 1 liter = 1000 x (1/12) = 83.33 ml
