don't worry, this one is very simple question and i've the solution of this question ckeck it...The diary man makes 37.5%
To make a profit of 37.5% the selling price would have been=6.4*137.5/100
= 8.8 ruppees
But he has sold the milk after adding water at Rs 8
He has added water to create value of 8.8 rupees
Hence water % added is (8.8-8)100/8=10%
The ratio of water to milk 10/100=1:10
