Effective amount taken out=-6+4=2 bottles.
Now 2 bottles correspond to 5% of the capacity.For 100% capacity, we will have 2/5*100 which comes out tp be 40.

tin contain 4/5 oil.
6 bottles of were taken and we pour 4 bottles in than
we get 3/4 of tin full
first we find how much 3/4th of 4/5th
4/5-x=3/4 we get 1/20
it mean if two bottles makes tin full 1/20th portion full (1/20=2) then to full tin 100% we needed 40 bottles
