Answer
The woman exerts more pressure and is more likely to dent a linoleum floor.
Make a rough calculation.
$$Pressure_{woman} = \frac{500 N}{5 cm^{2}} = 100 \frac{N}{cm^{2}}$$
$$Pressure_{elephant} = \frac{50000 N}{5000 cm^{2}} = 10 \frac{N}{cm^{2}}$$
Our approximation shows that the woman exerts about 10 times the pressure of the elephant on the floor.
