The CRT is going to be the big power consumer here.
Does the CRT monitor list it's power consumption on its nameplate, somewhere on the monitor housing?
... I think I better ask. Are you actually using a CRT monitor, or a regular flat-screen monitor.
CRT means 'cathode ray tube', which are pretty obsolete these days. Maybe you're using the term 'CRT'
generically, and don't actually mean the old-style cathode ray tube?

a 7.2 Ah battery can supply 360mA for 20 hours. At a higher current you will get less than 7.2Ah.

if you're powering something requiring 625VA, the battery might last 5 minutes.

Rritesh, we're not here to do your homework (which I suspect this is).

you haven't given enough info
is the 12V battery going to feed an inverter to 240V for the monitor and computer ?

yes 12V 7.2Ah it work for ~5min at 220V rated.
