Expert Answer:

Pressure = Force / Area 
 
pressure under smaller piston begin mathsize 12px style equals space fraction numerator 0.6 over denominator 0.2 end fraction space equals space 3 space N m to the power of negative 2 end exponent end style 
 Force on 200 sq.m area piston is = 3 x 200 = 600 N = 60 kg wt
