Question

A milk-man mixes water equal to

16.66% of the milk that he has. Further he

sells at a mark-up of 20%. Find his profit

percentage, if water is available free of

cost.​

Answer 1

Step-by-step explanation:

Say 1 litre costed 100 ..

Now with profit of 16.66 or 50/3 %, 1 litre should cost 100+50/3=350/3..

So for 350/3, we get 1 litre.

And for 1, we get 3/350 litre

Finally for 100, we get 100*3/350=300/350

So milk is 300/350 or 6/7 and water will be 1-6/7=1/7=14.28%
