By using boyles law
P1v1=P2V2
0.25x200=p2x300
50/300=p2
5/30=p2
p2=1/6

Answer:
The round piece of cloth on their heads increases the area on which the force (weight of the load) will act. We know that, the pressure is inversely proportional to area. Therefore, increase in area reduces the pressure and this helps the porter to carry the heavy load easily.
