@Dhiraj singh chauhan sir, I want you to look at the question no. 5 in your course. Here the numbers 16 (Milk's ratio) and 81 (mixture's ratio) both are square numbers, hence we can do it by root over. but what if there is a question which is not a perfect square number ( eg 17 in place of 16)? Please help me out with this.

It is getting decreased...
At end of 1st step, Milk:Mixture is 3:4...
2nd step, Milk:Mix is 9:16...
3rd step, 27:64...
3:4 < 9:16 < 27:64
