Answer : 2. "11:9"
Explanation :

Answer: B) 11:9 Explanation: From the given data,   The part of honey in the first mixture = 1/4   The part of honey in the second mixture = 3/4   Let the part of honey in the third mixture = x   Then,   1/4             3/4              x   (3/4)-x     x-(1/4)    Given from mixtures 1 & 2 the ratio of mixture taken out is 2 : 3   => 34-xx-14=23   => Solving we get the part of honey in the third mixture as 11/20   => the remaining part of the mixture is water = 9/20   Hence, the ratio of the mixture of honey and water in the third mixture is 11 : 9 .
