Correct answer:

a =  25 %
b =  30 h
c =  12.5 %

Step-by-step explanation:

p=300 Kc/h v=p+p/3=300+300/3=400 Kc/h  h2=60 h h2 = h1h1/3 h1=h2/(131)=60/(131)=90 h  a=100 vvp=100 400400300=25%
b=h1h2=9060=30 h
z1=p h1=300 90=27000 Kc z2=v h2=400 60=24000 Kc  c=100 z2z1z2=100 240002700024000=225%=12.5%
