A station supplies 250 kVA at a lagging power factor (p.f) of 0·8.

A synchronous motor is connected in parallel with the load. If the combined load is 250 kW with a lagging p.f. of 0.9, determine : (i) the leading kVAR taken by the motor. (ii) kVA rating of the motor. (iii) p.f. at which the motor operates.
