There is no induced EMF in non-coductor . Induced EMF is due to magnetic force  " q( v × B) " acting on free electrons in conductor.
 
No free electrons in non-conductor and hence no induced EMF .
 
Given proedure to solve the problem and the answer are perfecly corrrect.

A 200 V, 50 Hz supply is connected to a resistance (R) of 20 Ω in series with an iron cored choke coil (r in series with L). The readings of the voltmeters connected across the resistance and the coil are 120 V and 150 V respectively. Find the resistance “r” of the coil (in ohms). Also find the power lost in the coil (in watts)
