from what i understand
method 1
when distributing the profit from the profit distribution account you distributed straight to each partners capital account
method 2
you distribute the profit straight to a partners retained profit account
this means that under method 2, the capital accounts never change for the partners, hence it is easy to see at all times what was the initial investment of each partner
but having said that, i still dont know which mehod to use in questions, i guess if there is a retained profit account then u use method 2, is that right?
