An inductor and a resistor are connected in series to an ac source. The current in the circuit is 500 mA if the applied ac voltage is 8 \sqrt2V at a frequency of 175/\pi Hz and the current in the circuit is 400 mA if the same ac voltage at a frequency of 225/\pi Hz is applied. The values of the inductance and resistance are respectively

Correct Answer is : 60 mH, √71 Ω
