That is going to depend on a lot of things most notably which engines, and in what configuration, are installed. There are significant differences.
Also what -200 are we talking about. There were more than one wing type and a few companies doing the construction/conversion so there's an effect on fuel burn there too.
If you can't answer those questions I'll see if I can come up with the generic answers for you.

Well the 727-200 burns 4500kg in total per hour whilst holding at 1,500ft in ISA and 4,000kg in total per hour whilst holding at 25,000ft in ISA+10, so 3000lbs per hour per engine sounds about right as a ballpark figure.

I have heard it rumoured that Kelowna Flightcraft here in Canada has different numbers for pretty much every 727 in its fleet such is the degree of modification to be found on 727s. If you work it out with all different engine, wing, winglet and fuel tank options that effect the MTOW and weight and balance you could get 20 different answers for 20 different aircraft. Fun stuff.

For 727 100 and 200 (JT8D engines)
Depending on their weight - their fuel flow in cruise could be as high as about 9,000 lbs per hour (190,000 lbs cruise weight) and as low as 7,000 lbs per hour (about 110,000 lbs cruise weight)...
Their fuel flow 100 or 200 are same at equal weight... no difference really...
