Correct Answer: South, 185 m
Solution : Firstly, we will draw the diagram as per the given instructions –
From the above diagram, the distance between her starting point and the endpoint = 100 + 85 = 185 m As she can see her shadow now, that means she is facing the west direction (During the morning, the Sun is in the east direction and the shadow falls on the opposite side of the sun, i.e., the west direction.) Now, on comparing her movement's direction frame with the general direction frame, it can be concluded that the entry gate of her house is facing the south direction.
So, the entry gate of her house faces the south direction and the distance from her current location to her home is 185 m. Hence, the first option is correct.
