Appointment of MD - urgent !

Hello members

Please confirm me on this.

1. Can an NRI ( non resident ) be appointed as MD of a pvt ltd co. if not , what if he satisfies to be resident by being present for 182 days?

2. For the appointment of MD in a public co , he needs be a resident and the explanation provides for being resident he needs be in India for previous 12 months continously.

Now if an NRI , non resident , is appointed as MD of a pvt co , whose articles are satisfied on this, and that pvt co gets converted into public , would the appointment of MD gets void.

would the MD be required to vacate the office of MD after conversion.
