  • Question
  • 640 ml of a mixture contains milk and water in ratio 6:2. How much of the water is to be added to get a new mixture containing half milk and half water?


  • Options
  • A. 360 ml
  • B. 320 ml
  • C. 310 ml
  • D. 330 ml

  • Correct Answer
  • 320 ml 

    Explanation

    Here total parts of milk and water in the solution is 6+2 = 8 parts.

    1part = 640/8 = 80

     

    old mixture contains 6parts of milk and 2 parts of water(6:2).

     

    To get new mixture containing half milk and half water, add 4parts of water to the old mixture then 6:(2+4) to make the ratio same.

    i.e, 4 x 80 = 320 ml.
