The excess pressure inside any soap bubble is given by the expression,

P_{excess} = \frac{4 T}{r}

P_{1} = \frac{4 T}{4} P_{2} = \frac{4 T}{5}

The difference between the 2 pressures will account for the radius of the new surface

P_{1} - P_{2} = \frac{4 T}{r}

\frac{4 T}{4} - \frac{4 T}{5} = \frac{4 T}{r}

Solving, gives

r = 20 cm
