a dairyman pays rs6.4 per liter of milk . he adds water and there by making 37.5% profit. find the proportion of the water to that of the milk recieved by the customers?

• c.p of 1 lit milk = 6.4 rs
  and he is making profit by adding some quantity of water and selling the mixture at c.p.
  so we have to find the quantity of water nd milk in the mixture.
  so pure milk will be of worth = 6.4 - 6.4*37.5/100 = 4 rs
  so milk in 4 rs = 4*1/6.4 = .625 lit.
  so the remaining part will be the water which is = 1-.625 = .375 lit
  so the ratio of water to milk in the mixture is = .375 : .625 = 3:5 (answer)

• c.p of 1lit of milk- rs 6.4
  s.p of 1 lit of mix- rs 8.8
  therefore ratio would be 2.4/6.4= 3:8

• price of 1 lit milk is 6.4rs
  after adding the water total price is 8.8rs(6.4*1.375)
  now quantity of water will be calculated
  so water is sold at price of milk
  let we take quantity of water is x lit
  we know
  6.4 rs = 1 lit
  (8.8-6.4)rs=2.4/6.4=.375 lit
  so ratio of water to milk=375/1000
  =3/8
