Gst registration in case of reverse charge & normal charge

A person is running cars on uber/ola & giving car on hire of its own.

Turnover in uber/ola is estimated to be 11 Lakhs and turnover in hire is estimated to be 12 Lakhs. So the aggregate turnover will be 23 Lakhs.

NOTE: Uber/ola is paying GST under reverse charge.

Now my question is the person is required to get register in GST?

If yes, than how he will show the above transaction in GST return i.e whether he has to show only the transaction of car given on hire or he have to show both the transaction.

Thanks
