Explanation:

A Governor is appointed on the advice of the Union Council of Ministers, or in reality on the advice of the Prime Minister. For the President to consult the Chief Minister of the concerned state, before the appointment of a Governor is not a constitutional requirement. But a healthy convention grew up that the Chief Minister was consulted. But in the case of appointment of several Governors, this convention has not been obeyed.
A Governor may be simultaneously assignee to more than one state. Thus, on many occasions, the Governor of Assam was also the Governor of Meghalaya, Nagaland, Tripura, etc.
A Governor is appointed for a period of 5 years. The President, if he so pleases may extend his tenure. A vacancy in the Governor’s post arises, if:
(a) when the Governor completes his tenure,
(b) resigns,
(c) dies in office, and
(d) is removed from office by the President.
The Governors also have often been transferred from one state to another.
