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.
