    Solution

    Quantity of milk in 164 litre mixture = 17/(17 + 24) x 164= 17/41 x 164= 17 x 4= 68 litresQuantity of water in 164 litre mixture = 164 - 68 = 96 litresPercentage of milk in the initial mixture = 68/164 x 100 %Quantity of milk in 82 litre mixture = 17/41 x 82 = 34 litresQuantity of water in 82 litre mixture = 82 - 34 = 48 litresQuantity of milk in the final mixture = 68 - 34 = 34 litresQuantity of water in the final mixture = 96 - 48 + 123 = 171 litresPercentage of milk in the final mixture = 34/(34 + 171) x 100= 34/205 x 100 %Required percentage = [68/164 x 100]/[ 34/205 x 100] = 250 %
