How much of the 1914 Royal Navy survives to 1920?

How much of the pre-1914 Royal Navy would still be present if war began in 1920?

Nearly all dreadnoughts would survive, with the oldest ships in reserve or Dominion service and many pre-dreadnoughts already retired.

The surviving ships are redistributed by age and usefulness rather than scrapped wholesale. Lord Nelsons and perhaps some King Edward VII- and London-era ships may remain as reserve units, while older dreadnoughts can be transferred to Dominion forces or held for wartime activation.
