Answer 1

Answer: (B)

$10$

Sachin starts from A goes $30$ m North to reach B.

From B, then turns right and walks $40$ m East to reach C

From C, then turns right, facing South and moves $20$ m to reach D.

Again he turns right thus facing West and moves $40$ m to reach E

So he is in line with the starting point at a distance of ($30-20$) = $10$ m
