In a series LCR circuit $R = 200 \Omega$ and the voltage and the frequency of the main supply is 220 V and 50 Hz respectively. On taking out the capacitance from the circuit the current lags behind the voltage by $30 ^ { \circ }$. On taking out the inductor from the circuit the current leads the voltage by $30 ^ { \circ }$. The power dissipated in the LCR circuit is
(1) 305 W
(2) 210 W
(3) Zero W
(4) 242 W
