Combination of Resistors

Consider the combination of resistor, The equivalent resistance between a and b is

A 5Omega resistor is connected in series with a parallel combination of n resistors of 6Omega each. The equivalent resistance is 7Omega . Find n

A series combination of resistor (R), capacitor (C) is connected to an AC source of angular frequency omega . Keeping the voltage same, If the frequency is changed to Omega/3 , the current becomes half of the original current. Then, the ratio of the capacitance reactance and resistance at the former frequency is
