On a modern high-bypass turbofan engine, typically what percentage of the thrust comes from ...?

... the cold fan, compared to the hot jet thrust leaving the low pressure turbine?
I am just asking out of general interest (I've just been to an airshow) so am just wanting a rough idea. By 'typical' I am thinking of a newly built commercial jet airliner engine at typical cruising airspeed, throttle and altitude.

Typically, nowadays, 70-75% is going though the low pressure turbine, and 25-30 % through the high pressure turbine, compressed, and ignited.
With the next gen engines though, that figure will most likely become what the previous answerer said. 80%-85 % bypassed.
