A man buys spirit at Rs 60 per litre, adds water to it and then sells at Rs 75 per litre. What is the ratio of spirit to water if his profit in the deal is 37.5%?

• 10 : 1
  
  If man buys 'x' liters of spirit @60 Rs/liter then cost price =60x
  If 'y' liters of water is added to it, then Selling Price @75 Rs. /liter=75(x+y)
  As profit is 37.5%, so selling price is 137.5% of the cost price, hence 60x*1.375=75(x+y)
  82.5x=75x +75y
  7.5x=75y
  x/y=10

  SP = 75, => CP = 75*(100/137.5)=600/11
  water spirit
  0 60 ----------actual CP
  600/11 ----------------expected CP
  60-600/11 : 600/11-0 -----------by criss-cross ,we get ratio
  => 60/11 :600/11
  =>1:10
