Ratio of honey and water in mixtue A = 1 ∶ 2
Ratio of honey and water in mixtue B = 3 ∶ 2
Ratio of honey and water in mixtue C = 5 ∶ 4
We have to equal quantites of all mixture and A, B and C taken in the ratio 3 ∶ 2 ∶ 1
Ratio of honey and water in mixtue A = 1 ∶ 2 = 3 unit × 15
Ratio of honey and water in mixtue B = 3 ∶ 2 = 5 unit × 9
Ratio of honey and water in mixtue C = 5 ∶ 4 = 9 unit × 5
New ratio of honey and water in mixtue A = 15 ∶ 30 = 45 unit
New ratio of honey and water in mixtue B = 27 ∶ 18 = 45 unit
New ratio of honey and water in mixtue C = 25 ∶ 20 = 45 unit
Ratio of honey and water in mixtue D = (15 × 3 + 27 × 2 + 25 × 1) ∶ (30 × 3 + 18 × 2 + 20 × 1) = 62 ∶ 73
Total quantity of the mixtue = 62 + 73 = 135
Total quantity of honey in mixtue = 62
Percentage of honey in the mixtue = [62/135] × 100 = 45.92% ∼ 46% (approx)
