      Solution

      ATQ,

      Total quantity of resultant mixture = 480 + 20 = 500

      Quantity of milk in resultant mixture = (3/5) Γ— 500 = 300 litres

      Quantity of honey in resultant mixture = 500 – 300 = 200 litres

      Since, quantity of milk remains constant.

      So, quantity of milk in initial mixture = 300 litres

      And, quantity of honey in the initial mixture = 480 – 300 = 180 litres

      So, ratio of quantity of milk and honey in the initial mixture = 300:180 = 5:3

      So, m = 3
