Step-by-step explanation:
Lets assume we have 10 litres of milk and hence it will cost Rs 85 (CP)
Say, x litres of water is added to the mixture and there the final volume becomes (10+x) litres.
Given that he sells the mixture at cost price and gains 11.11% i.e. 1/9.
He sells this at Rs (10+x)*8.5 (SP)& makes a final profit of 1/9 %.
Therefore by equating the values in the formula ( SP/CP-1 = Profit% ) we get x= 1/9= o.111 litre
