You first find the impedance of the feeder system. Then do the same with the motor, an you have two impedances that can be calculated the voltage drop over.

Sir how can i calculate these impedances by using the given parameters?

Assume the short circuit power is dropped across the impedance of the 400 V network. From power and voltage you can calculate impedance.
With this impedance calculate voltage drop from the motor.
