do you know which one exerts more pressure an elephant walking on the ground or a girl walking on the ground with high heels on her feet??? Try if you can't I can with a appropriate reason....

There is no definite answer! 
This question depends on the size of the sole of the shoe and the size of the elephants foot as well as their weights/forces acting on the ground due to gravity. The pressure = force/surface area.

The elephant exerts more forces because it has a greater weight. However, the surface area of its foot is also greater.

The girl exerts a small force but at the same time, has a small surface area that the force is acting on. 

If we were to plug values into this:

The elephant exerts a force 100 Newtons and has a total foot surface area of 50 cm squared. Its force = 100/50 which = 2. 

The girl exerts a force of 10 Newtons (a lot less) and the total heel surface area is 5 cm squared. Her force = 10/5 which also = 2.

So to conclude, their pressures rely upon their weights and the surface areas of their feet/shoes.
