Problema incrível de circuito RC envolvendo tempo de carga e descarga de um capacitor

Given the RC circuit below, containing two switches S1 and S2. Switch S2 is closed and S1 remains open until the capacitor acquires a charge q0. Then S2 is opened and S1 is closed simultaneously until the capacitor has a charge q_0/2, this occurring at time t1. Now S1 remains open and S2 is closed until the charge on the capacitor is 3q_0/4, this occurring at time t2. Determine the ratio t_1/t_2.
