Father's new mass will be 9.174 kg. The force was acting on the chair is 90 N. The reaction force is divided in four legs of the chair as 22.5 N.
What is the difference between mass and weight?
Mass of the body is defined as the amount of matter a body has. It is denoted by m and its unit is kg. Mass is the quantity on which a lot of physical quantity depends.

Weight is change according to the place or surroundings, while the mass of the body is constant everywhere.
If the initial mass is assumed to be 60 kg, then the if father gained 30 N father's new mass will be 9.174 kg.
The force was acting on the chair is 90 N.The reaction force is divided in four legs. of the chair as 22.5 N.
Hence, father's new mass, force was acting on the chair and reaction force will be 9.174 kg, 90 N and 22.5 N.
