3/5 part of a kerosene tin is filled. if 6 bottles are taken out of it and 3 bottles are filled again, then half the tin is full. what is the capacity of the tin?

• 30 bottles
  
  Initially tin is 3/5 filled
  
  6 bottles are taken out and 3 bottles are filled again
  ====> 3 bottles are taken out
  
  (3/5 of tin capacity - 3 bottles = 1/2 of tin capacity
  (3/5 - 1/2 ) of tin capacity = 3 bottles
  1/10 of tin capacity = 3 bottles
  ===>tin capacity = 30 bottles
