Regarding Eb bill

Yes, allowed as personal expenditure..

Full amount can be taken as drawings and half amount can be paid by father

Half amount can be paid by son?

Yes, allowed if the amount is not claimed as an exemption.

Ok sir thank you so much 

Its not taken in any exemption 

Only in drawings in both father and son account 

Ok sir 

Yes, allowed....                 

It is a personal family arrangement in a joint family.

So no tax implications
