Lokesh moves 120 m in north direction from his home and then turn right. After walking 110 m he reached Yes Bank. Then he turns right and moves 90 m to reach the coffee shop. Then he moves 100 m in north-east direction to reach Market, which is in the east direction of Yes bank. From there he moved 150 m in south-west direction to reach his college.

Explanation:

Note: Colleges of both Kishore and Lokesh are in east direction with respect to their room.
Therefore, Lokesh's college is exactly in the east direction of his room.
Now we know that Lokesh's college is in east direction with respect to Lokesh's room.
Using Pythagoras theorem, we get:

√50²-30² = √2500-900 = √1600 = 40 m

From this, we'll calculate the shortest distance between Lokesh's room and college = 110m – 40m = 70m

Hence, option B is correct.
