Now,there were 4 post graduates in sociology and one in commerce. All have been accounted for. Hence,Vimla is not a post graduate either in sociology or commerce.
Among Kamla, Amala, Komala and Nirmala there are 2 bank employees. We already know that Kamla is a bank employee and Amala and Komala are not. Hence, Nirmala must be a bank employee too. Hence, all the three bank employees are accounted for too.
However, there are still two tennis players unaccounted for. The updated information can again be shown in the form of a table:
