In some quantity of ghee.60% is pure ghee and 40% is vanaspati.If 10kg of pure ghee is added, then the strength of vanaspati ghee becomes 20%.The original quantity was????

• let initially the quantity was X kg.
  after adding 10 kg of pure ghee it becomes (X+10) kg.
  now after adding pure ghee the total content of vanaspati remains constant.
  so, (x+10)*(20/100)=X*40/100
  x= 10 kg. (ans)

• Initially, G:V=3:2
  After adding 10 Kg of Pure Ghee, G:V=4:1
  To maintain the proportion of V,we write the above ratio as 8:2
  So,3:2 & 8:2
  Therefore,Change of G=(8-3)=5
  Now apply Unitary Method,
  For 5 Change is 10 Kg
  So,for (3+2)=5 Change is (10/5)*5=10
  Ans. Original Qty was 10 Kg.

• Simply 10kg.
  (taking X )
  
  
  another way -
  
  40% reduced to 20%. so 1/2 reduced.
  so total amount = 10/(1/2) = 20
  added amount = 10kg
  so previous amount = 20-10 = 10Kg.

• let the total b 100..
  then pure=60 , vanaspati=40
  10kg added so.. vanaspati becomes 50
  20%(50)=20/100*(50)=10
  
  so 10 is the answer
