A^plunger /A^piston =?

A dentist's chair with a person in it weighs 2000 N. The output plunger of a hydraulic system starts to lift the chair when the dental assistant's foot exerts a force of 42 N on the input piston. Neglecting any difference in the heights of the piston and the plunger, what is the ratio of the area of the plunger to the area of the piston?
