Pure ghee costs Rs 100 per kg. After adulterating it with vegetable oil costing Rs 50 per kg, a shopkeeper sells the mixture at the rate of Rs 96 per kg, thereby making a profit of 20 %. In what ratio does he mix the two ?

a. 1 : 2
b. 3 : 2
c. 3 : 1
d. None of these

• Ans is B
  profit=96 *20/100 = approx 19 rs.
  so cost price= 96(selling price)-19 =approx 77 rs
  
  Now apply hit and trial.
  if 3:2 then total 5 parts are there (3 of ghee + 2 of oil).
  3 parts of ghee means 60% of total solution while 2 parts of oil means 40% of total solution.
  
  so cost price will be as: 100*60/100 + 50 *40/100 = 80 ~=77

• answer is B
  we can do it by alligation
  
  SP of mixture is 96 making profit 20%
  therefor CP is 80
  
  Now using alligation
  
  100 50
  /
  /
  /
  80

  /
  (80-50)=30 (100-80)=20
  
  so the ratio is= 30/20
  3:2

• using mixture and alligation:
  96*100/120=80/kg
  100 50
  80
  here 100-80=20 and 80-50=30...we will get 20 and 30 in cross multiplication so by solving further we get
  =30 =20=================30:20=3:2 Answer
