We could find answer by conventional way but is there any shortcut to find quick answer as conventional way is highly time taking.

Actually the resistance of a parallel circuit will be less than that resistor which has less resistance value).
So here R = 6800 ohms.
Internal resistance of l = 30 ohms.
And Resistance of capacitor = Very high value.
So the total resistance required of the circuit would be less than 30 ohms.
