30m East (turned right)
As we see it is forming a rectangle (opposite sides of 30 m are equal), the opposite side to 12 m is also 12 m (opposite sides of a rectangle are equal).
Thus, Pramila is 12 m far from here point.
Answer:
20 A you not option in that
Step-by-step explanation:
Pramila walked 30 m East and then took a right turn i.e. in South and walked 20 m and then took another right turn i.e. west and moved 30 m.
So, he made U turn covering the distance of 30 m.
Thus, he is in the same line i.e. towards South and 20 m far from the starting point.
Hence, option '20' is correct.
