A milkman would know this drill irrespective of his accuracy with ratios and numbers :-p
Well, Jokes apart!
Lets assume the total quantity of mixture to be 100ml
water - 25 ml, milk - 75 ml (original ratio of 1:3)
Proportion in target mixture of 100ml
water - 50 ml, milk - 50 ml
The mixture is homogenous, so any reduction will not change the original ratio. We aim to reduce the milk to 50 ml. Therefore we need to reduce the milk by 25 ml. When the milk in the given mixture is reduced by 25 ml, water reduces by original ratio 1/3*25=8.33 ml
total reduction = 33.33ml
after reduction water = 16.67 ml, milk = 50 ml
now add replace the reduced amount of mixture with equal amount of water you will get
water = 50 ml, milk = 50 ml
Now see what happens when you reduce by half
Total quantity of mixture reduces from 100 ml to 50 ml and using the original ratio principle
water - 12.5 ml, milk - 37.5 ml and now if you replace the reduced amount with water you will end up with
water - 62.5 ml, milk -37.5 ml
Now see what happens when you reduce by quarter i.e. 1/4
Total quantity of mixture reduces from 100 ml to 75 ml and using the original ratio principle
water - 18.75 ml, milk - 56.25 ml and now if you replace the reduced amount with water you will end up with
water - 43.75 ml, milk -56.25 ml
So now you know what is the most important part of mixture related puzzles…
