So putting it mathematically,
Baa = something (where something is undefined)
For the sake of simplicity, so we can do more maths, lets say that "undefined" is "infinity".
Since there cannot be two infinity, there could not be anyone same as Baa......How about splitting infinity....let's give a go....
Baa = Shilpa + Leela + Baby + BitGudia + BitMeenakshi + Harshad + Subodh + antiPravin
Ok that's fine, but above equation is still not correct, because infinity cannot be broken so the equation becomes,
Baa = (same as above) + infinity
, because, Infinity + 1 + 2 + 3 = infinity
So the conclusion is that responsibilities can be divided but still the house will not be run in the same manner like how Baa used to run it...because there is still a infinity to be added in the equation (as shown above)..and we all know that infinity is undefined.
So mathematically no one can run house exactly same as Baa.
(I tried to use Calculus, but thought it will make this too complicated).
