Well I don't know !
Let's work it out:

       Weight = (mass) x (local acceleration of gravity)

         117.6 N  =  (12 kg) x (gravity)

         Gravity on Planet A  =  (117.6 N) / (12 kg)

                                       =      9.8 m/s²  exactly

The gravity on Planet-A is so close to Earth gravity
that nobody could ever tell the difference without
making sensitive measurements.
They are essentially equal.
