My worksheet shows a question ' deduce the gravitational potential energy of two-mass system to be -GMm/r '.
I never heard of "two-mass system". What is it? How could I deduce it?

A "two mass system" is simply a system containing two discrete masses.
A single mass gives rise to a (gravitational) potential field surrounding it. The presence of the second mass in this potential field acqures "potential energy". The question asks for the potential energy possessed by such mass.
