It is required to find the pressure do you experience when you balance it on the tip of your finger that has an area of 1 cm square. Pressure is given by force acting per unit area. It is given by :

$P=\dfrac{F}{A}\\\\P=\dfrac{mg}{A}\\\\P=\dfrac{0.25\ kg\times 9.8\ m/s^2}{0.0001\ m^2}\\\\P=24500\ Pa$

So, the pressure experienced by the person is 24500 Pa.
