  • A) 1 : 2
  • B) 1 : 1
  • C) 2 : 1
  • D) 4 : 5
  • E) None of these
Solution

Solution : 4

(4) : Amount of milk left after first withdrawl

81 - 81/3 = 54Litre

Amount of milk left after second withdrawl

54 - 54/3 = 36Litre

Amount of water left = 81 –36 = 45

litre Ratio of milk to water in the new mixture = 36 : 45

                                                                   = 4 : 5
