60kg. Mass doesn't change. The force that mass exerts due to gravity changes. The force of gravity on her moon is approximately 1/6th thst of earth. So therefore the force or weight of a 60kg mass will be 10kg off weight (not converting to Newton's ofcourse).

The mass of the man would remain the same…
His weight would change. Assuming the man’s weight on earth is 60 N.
Since weight is a force, according to Newton’s second law, F = ma ( m = mass, a = acceleration due to gravity)
First lets find the mass of the man, as it is required to find his weight on the moon.
F = ma [taking a of earth as 10 m/s^2]
60 = m . 10 [divide 10 on both sides]
m = 60/10 = 6 Kg
Acceleration due to gravity on the moon is 83% less than the acceleration due to gravity on earth (1.622 m/s^2).
F = ma
F = 6 . 1.622 = 9.732 N
So a person weighting 60 N on earth would approximately weight around 10 N on the moon.
