Explanation:
Given
velocity of driver
=25 m/s w.r.t ground towards north
driver observes that rain is making an angle of
with vertical
While returning
=25 m/s w.r.t. ground towards south
suppose
=velocity of rain drop relative car while car is going towards north
=velocity of rain drop relative car while car is going towards south
z=vector sum of 
Now from graph



therefore magnitude of z is given by






Thus rain drops make an angle of
w.r.t to ground
